43 Best Fast Food Restaurants in Fullerton

“Teriyaki Express in Fullerton offers good, well-portioned, and reasonably priced teriyaki food. However, I must express my disappointment with the owner’s demeanor. It comes across as impersonal and unfriendly, which is unfortunate because I’m a loyal customer. If the customer service continues to be poor, they’ll lose loyal customers. 🇯🇵“

“I just had my first In-N-Out at this location and it was one of the best burger experiences I've had. They were so excited to treat a first timer and gave me some stickers! I'm from Ohio, and the closest we have is Five Guys, and this blows them out of the water! My wife is the local, so I followed her lead and had burgers and fries animal style! Everything was DELICIOUS! Thanks to everyone at the location! Everyone was very genuinely cheerful and nice! (went through at 11:00am, Sep 4th 2023)“

“Amazing Lotteria taste! Best burgers in Korea have finally come to Fullerton and are the best burgers here too! I got the bibim burger combo with onion fries and the bulgogi burger combo with cheese fries and also bingsoo cups! Everything was hot, fresh and delicious! Juicy bulgogi patties, so yummy and reminded me of my days in South Korea! I ate well, thank you!“

““Wow” Monday I went to restaurant and pre-ordered 20 meals for my guests who were going to be celebrated by daughters 2 year birthday. Mayra was great, friendly & professional but there was a misunderstanding on the date. Which of course I feel terrible about! But they accommodated my order for the correct date! Everyone enjoyed the food. Especially the bass fish with vegetables and rice plate! Fancy for 12.00. Large portions too!“

“Absolutely Fantastic Service 👍“

“I love this Carl's Jr it's my favorite one to go to... the customer service is outstanding and the food is great .. I'm a regular here and they treat me with respect and kindness... the restaurant is clean and the atmosphere is wonderful... if anyone is hungry come to this Carl's jr you won't regret it ..“

“The food was great, but we all know how normal it is to get ok service. Now and days (I’m 29) it’s a good experience if they are just normal… John was what I imagine old school service was like. You feel like he really wants you to be happy and I was delightfully taken back by his attitude. John is who you hope for every time you are receiving customer service. Thank you John!“

“I really had to take a quick moment to post a review on the service I received. The kind gentleman who served me at the drive thru was so sweet and personable. You really don't see that kind of service nowadays and I appreciated his warm, friendly demeanor. I wish I had his name to give a shout out. It was around 9am today (05-23-26). Thank you for your kindness!“

“Mario and all the works in the morning are amazing! I go almost everyday to get food for my brother because he’s special needs and loves Carl’s Jr and they’re always positive and in a good mood when taking my orders!! Appreciate them:)“

“Exelente las personas ahí son de lo más atentas y serviciales 10 de 10👍“

“I have gone through the drive-thru many times, but today was my first time dining inside.

There were plenty of open tables. I suspect that it's much busier during the day since it's next to a couple of office buildings. There was a booth in the corner that was perfect. I've been looking for places to study and this worked out well. I brought my earbuds to create my own ambiance. 🤭

It's very clean and well-lit. The women's restroom was also very clean.

I stepped to the counter to order a grilled chicken salad. The associate who took my order asked if I'd like to try the Cobb salad since it was one of the specials, so I ordered it ($5 cheaper than the grilled chicken salad). I was pleasantly surprised that a small drink was included.

Overall the salad was good. It was a generously sized salad and I brought half of it home for tomorrow. My least favorite part of the salad was the sad beige chicken 🫣 (it was probably boiled) it was sufficiently seasoned and tasted fine, but it lacked the beautiful brown color of pan sauted chicken and the smokiness of the grill...probably why I normally order grilled chicken. A little char on the chicken is nice, amirite? Next time I'll ask if they would substitute grilled chicken. 🤔

Anyhow, I also ordered my favorite item from Farmer Boys - the zucchini fries. They are huge! The order is essentially one large zucchini, quartered, battered and fried. So yummy. They're fresh and still slightly crunchy. It's served with ranch dressing and I usually request some yellow peppers to give it a little kick. Today I got a spicy ranch dressing for the salad and used it as dip for the zucchini fries. Honestly I'm probably going to ask for the spicy ranch instead of regular ranch in the future. If you like zucchini, I definitely recommend!“

“I don't have to say this to those who know me but I'm a regular at which ever Del Taco is nearest to my current job. Quick, clean, good tasting food, and the price is right. I am especially fond of the one on Rosecrans and Euclid. Overall, I think they must have a great training program there because I find the employees to be unusually courteous for a fast food place.“

“This is the Best Flame Broiler I’ve been to.
It’s amazing how the customer service can elevate a Franchise to the next level.
This business is 2nd to none.

See you tomorrow!

Thank you“

“I ended up getting tostilocos for my first time last Wednesday it was really good and if u don’t like stuff on it u can ask them not to put it also my sons father got a strawberry smoothie really enjoyed it and the next day we went back and got two michelaguas lol those were to die for and got everyone’s attention at church asked us where we bought it cause it looked like a real beverage but good since it wasn’t alcoholic haha and then my sons father got a açaí bowl original kind my sons father said he’d get it again :) I was able to get a mini keychain plushie from the claw machine on my first try I got it XD picture is on here as proof“

“Lisa was great she is very good with common schooling for every Wednesday and we always treated with a smile and a cheerful greeting LISA is incredible hard-working she southside sleeping he’s doing windows I wonder can be the 10 is the best. She’s a 20 send it.“

“I'm going to be 100% honest. The service is fantastic. The chicken is good but without their special sauce it would taste like the other chicken places. Their Texas toast is only toasted on one side which makes the bite mushy. For me their coleslaw needs to be blended more. The fries are so so. This is just my own opinion.“

“This is the only Flame Broiler with a drive-thru. I find it very convenient, as I don't have to stop and get out of the car. I just order, get the food and go. Excellent brown rice steak bulgogi with veggies. Always put on the bulgogi sauce. The red sauce is also very good. Friendly staff, too!“

“I just wanted to drop a review to say how awesome Cecilio is! Every time I visit this Subway, he goes above and beyond. Not only does he make a perfect sandwich (he doesn’t skim on the toppings and actually wraps it neatly), but his customer service is top-notch.“

“Really enjoyed it. Part of our Valentine's Day Celebration. Thought it was a strange request, but whatever the Love of my Life wanted.“

“I ordered online and when I came in my order wasn't ready. Found out they were out of wraps. They let me know, offered on bread, picked my bread and they made them up quick and correct. They are a busy store, bare inside and kind of boring but the food and the workers are where it's at.“

“el cocinero un güero muy amable apenas nos miro nos saludo muy amable mente. el pollo me lo dio a mi gusto como a mi me gusta un joven gringo muy amable .....no puedo de sir lo mismo de la mujer que estaba trabajando ..le dijimos gracias y ni siquiera nos contesto... el lugar muy limpio !!!“

“I got a western bacon cheeseburger meal & everything was delicious! Keep up the good work Maria working the drive thru at store # 1100635 on Halloween 2025!!

In the 90's, Carl's Jr was the best burger spot I could walk to, but 10-15 years ago the food changed. The buns were stale, fries weren't ever hot, onion rings were rubbery, the soda was watered down & the quality was awful. I was bummed, but I never gave up!“

“I stopped in here to pick up my lunch on my way to work, yeoshi took my order up front he was the most pleasant and wonderful person he made me feel welcomed he even offered me a glass of water while a waited for my food if there was more than 5 stars I'll give it to him as well . Thank u.“

“first time trying & it was soo good I ate it in the car !!! cant wait to try something different. the staff was quick & friendly it's not cheap but what is now a days? plus I think you @ least get your money's worth.“

“It was the bomb. And they hooked it up with fries. Thank you for the extra ketchup“

“Yummy 😋 very gooood tacos“

“Does Del Taco got a remodel this past year and let me tell you, it is really nice. The only downfall is the drive-thru but that is more of the parking lot issue and not really Del Tacos fault. Food here is consistent with any other Del Taco you would go to. The only reason the food here did not get five stars is because I ordered the party pack and my bean and cheese burritos were not really hot. That was a bit of a bummer biting into a burrito and getting very lukewarm beans. I asked for well done fries and they were delicious :)“

“Tge only place on this corner where you can get food this cheap or this late. It's definitely fast food but I end up eating here a lot. The Jack Wrap and meat kiver's buritto are probably the best two things on the menu. And the Jack Wrap is a decent amount of food for less that $4“

“Chas Mcgee should get a fat raise!. Very friendly and fast..“

“It very frienly custumes service emloyes go above cleanneess“

“Got a cheeseburger, breakfast burrito and biscuits & gravy. Cheeseburger was great and what I would go back for. Breakfast burrito was ok and would get again if craving for one. But biscuits and gravy I would skip. I’m kind of a snob when it comes to biscuits and gravy and these are just generic.“

“I came before closing so the restaurant was quiet. I ordered the half and half bowl and it was more than satisfying. The beef and chicken were equally delicious. For added flavor you have to add the magic sauce.. Not spicy - just flavorful. I would like this place more if they had a location near Chicago. Very good restaurant. Very good food. Come check them out.“

“No longer have Krispy krunchy chicken. No more“

“They were AMAZING!! Do they still have them??“

“The team is amazing here. I’ve always appreciated their efforts in making the order right. Truly enjoy the atmosphere here at the store. The remodel on the store looks amazing. Lastly I want to mention Elydia for always being quick to helping me and other customer quickly anytime there were concerns. You make my trips to this store amazing. Thank you for your constant support!“

“Krazy good! My wife and I often go for the #2 deal there. Thigh and wing, potato wedges, and biscuit. The meat has a Cajun injected seasoning (?), is moist and crunchy with a great coating. It’s my favorite in town. The potato wedges have a yummy coating on them as well, and the honey butter flavor to the biscuits is incredible. It’s all so good!“

“Let's get one thing straight, Taco Bell ain't nothing but a thang. Southern California Icon. This particular location in Fullerton is small but nighty, three person crew at mid day running it. Drive through was bountiful, inside dining was well represented. Manager/Shift lead was on point. Young worker on register was new and wide-eyed, filled with hope and a yearning for whatever his future may bring. Cook was quick and attentive, a real pro. Taco Bell, a Southern California Icon and this Fullerton location is a testament to the Taco Bell legacy.“

“I don't understand all the negative reviews... Basically I go every morning get coffee.. apple pie or which ever is the season item..and a sausage briske.. morning crew always friendly.. food is hot.. service is good... Bathrooms clean even with the homeless...And it's fast food restaurant..Remember we all have bad days..But give respect / Get respect..“

“I ordered top 5 of the burgers. lovely lunch...too hungry.“

“Good place for a family who has different tastes. Two resurants in one and a McD across from it. So lots of options all in one place. Food is ok. It's fast food if we're being honest but chicken, burritos, and next door is burgers. Everyone can have what they want. Good time 👍“

“This is a great place to eat. Newly remodeled and very tastefully done. Food and service is really awesome“

“We leave in Fullerton and there is McDonald branch instead of going there we drive this branch to have a good breakfast, cause the crews working here are nice and the coffee they served is fresh , I appreciate the way they served us with good smiling face like Maria and Michael that I remember their names … I highly recommend to my friends to have their meal in this branch .. all the staff are nice and place are in order and clean“

“Missed the route 30 bus so wanted to try it out in my 40 mins wait. Ordered a small flatbread vegetarian sub and it was fantastic (no soggy sauces or old veggies). There is dine in space for 30ish people and each table is wheelchair accessible. The dining area was sparkling clean so was the men's restroom (except the last guy used the toilet tried to clog it up with napkins because that's a monkey). Will drop by more often 5/5“
