The Brothers burger is large and very good. The avocado pieces are huge. The burger wasn't over cooked. Everything is fresh.

We will try other items next time.

I would recommend this place.

P.S. where is the Sister burger?“

“Great food, great service, clean restaurant, and reasonable prices. What else is there to ask for? When i walked in i was greeted and someone behind the counter immediately stopped what they were doing to assist me and take my order. I got the bacon cheeseburger just the burger itself to dine in. It was served quickly and at a pleasant temperature. The ingredients were fresh and the bacon was thick and they do not skimp on the bacon!! The burger was delicious. The restaurant was clean and the decorations are adorable. I had a great experience here as my first impression and I recommend this place to anyone. Great job mister Andy.“

The double drive thru was a new experience for me as there was no indoor dining on this warm autumn day. I did manage to find some shade at one of the 5 tables. The only thing I might suggest would be instead of umbrellas, have a patio setting. Build a ramada/gazebo for guests to enjoy the small property. The food did take a minute to come out, but I understand they cook everything to order and had long lines of cars. Overall, I was not disappointed with visiting a go to chain!“

To elaborate what I meant by good quality fuel. A lot of these gas stations tend to have a very low quality fuel that don't get you high mileage. What's on my gas tank is what I get. I haven't seen these numbers where I live at so I know that I'm getting 400 mi out of this car.“

“J J Grill was recommended to me by my coworkers and I’m really glad I gave it a try! I ordered the chicken teriyaki, which came with cabbage, rice, and my choice of french fries or salad. I went with the fries, and they were so good, hot and crispy. The chicken was flavorful, though it was a bit heavy on the sauce, which soaked into the rice. Not a big deal, though next time I’ll just ask them to go easy on it.

The staff were super friendly and made the experience even better. Overall, great food, good portions, and a welcoming vibe.“

“Been to countless Denny’s locations in my life but this would be one of my more memorable ones. The location was moderately busy but that didn’t stop the staff from providing top notch service. Everyone seemed to be getting served and tended to in a timely manner and I saw our server get multiple thanks and kudos from departing guests. My wife is a bit picky on food and she had the pot roast. She said it was very flavorful and moist (she even packed her leftovers to go which she only does when she’s genuinely happy with her food). She also ordered a side of zucchini and squash (oh no…) and said the only place she’s had better is mine at home (only because practice makes perfect LOL) or a pricey steakhouse we go to on occasion. I had the Lumberjack slam and when I tell you every single component was perfect, I mean perfect. Perfectly cooked meats, perfect over medium eggs, and heavenly hash browns. I upgraded to cinnamon roll pancakes and don’t regret it one single bit. Fluffy and light, perfect amounts of salty butter, cinnamon, and glaze. It was like a Cinnabon on steroids 😆. I sincerely hope this is the norm because if it is, I may have just found my new go-to diner when I need a great meal.“

“While waiting for a flight from ONT International. I decided to stop and enjoy a real breakfast. I’m on Atkins and don’t love meat. I was happy to find this thick veggie omelette. As Atkins doesn’t allow for the standard breakfast potatoes and toast, the server was gracious enough to bring me a lovely salad. The veggie omelette was thick with green and red peppers, onion and mushroom. It was light on the cheese which I appreciate. The salad was fresh mixed field greens, tomato, shredded cheese and a wonderful ranch dressing. The kitchen staff was savvy enough not to put on the croutons. This was a great stick-to-your-ribs breakfast. Service was prompt and I noticed pilots in uniform enjoying breakfast as well.“
