33 Best Fast Food Restaurants in Fullerton

“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)“

“Delicious 😋 Best chicken bowl I've ever had!! The sauces they have are perfection and the salad surprised me!! They have milk tea bobas and freshly squeezed lemonade its a great place to grab for lunch or dinner and the staff is awesome very kind and helpful 😊“

“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!“

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

“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.“

““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 👍“

“Yummy 😋 very gooood tacos“

“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“

“**Excellent Food and Customer Service**

I visited Farmer Boys in Fullerton last Saturday, August 22, 2026, and had a very enjoyable experience. I ordered an omelet with onion rings and French fries, along with a crispy chicken burger cooked well-done. Everything was excellent and very enjoyable.

I would especially like to recognize Alfredo, who prepared my food and provided excellent customer service. His professionalism and attention to customers really stood out.

I have also read some other comments from customers complaining that an employee was taking a break and did not immediately attend to them. I think it is important to remember that customers and employees have different roles. Employees are entitled to take their legally required breaks and have moments to relax. They are there to perform their jobs, but they are not the owners of the business or required to be at the complete service of customers every moment.

Let's show employees the same respect and understanding that we expect to receive as customers. Overall, my experience at Farmer Boys was very positive, and I appreciate Alfredo and the rest of the staff for their hard work.“

“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!“

“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 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.“

“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!“

“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:)“

“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.“

“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 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“

“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 ..“

“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“

“I haven’t been to a Carl jr in a while but when I did come the cashier I think her name was nori, she was so kind and was very helpful when answering my questions. She definitely brings a welcoming spirit. I will definitely be coming back when I’m craving a burger!!!!“

“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.“

“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.“

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

“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 love the people there and I am going to be seeing them for awhile since I’m
Going to college there. I recommend this place best service best food and always perfect atmosphere so come eat here if you’re in Fullerton if you’re craving a sandwich“

“Came by to try the promotional Mexican Pizza. The restaurant feels much more modern than I remember from when I was a kid, which was a nice surprise. Customer service was average—nothing outstanding, but nothing to complain about either. The food was exactly what I expected from Taco Bell: good, satisfying, and somewhat affordable, though not anything amazing. Overall, it was a solid visit, especially if you’re craving some classic Taco Bell favorites.“

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

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

“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.“

“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.“

“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 came in the drive thru at 3 something in the morning July 17 the cashier was so nice took my order really good my food came out fresh hooked me up with lots of cheese 😜 I was really craving the cheese from here they did they perfect wonderful job“
