One of my family's favorite burger joints in the neighborhood is this one. Most of the food is enjoyable to us. It also has a drive-through, which makes it really convenient. Some of our favorites are included below. This hamburger is simple but incredibly tasty! Also essential is the chicken salad! Actually, I think it's the best thing on the menu. It features a number of toppings, including cheese, tomatoes, cucumber, and boiled eggs. We also tried the chili cheese pastrami fries for the first time. The pastrami was a bit dry, but they were still tasty. The workers are also polite and they keep the inside of the restaurant fairly clean.

Me and my son decided to try this place after we saw it in Instagram we were hoping for the best and we weren't disappointed we wet very happy with the service Cinthia the cashier was very nice and gave me good suggestions on what was good since it was our first time there. Finally we got our food I ordered the Pastrami Fries and a hamburger combo my son ordered a hamburger combo and chili cheese fries , my fries needed more cheese so I asked for more and I asked Miguel to add more he added more at no extra charge thank you Miguel we highly recommend this place gracias Miguel y Cinthia .

Very clean eating area. Food is delicious from burgers to breakfast to chili cheese fries. Prices are very reasonable and affordable. Employees are very nice and friendly. Definitely one of my favorite places to eat.

Watching a foodie review them on YouTube , Great food very friendly service .will definitely stop again .

The food was good but I had just activated my credit card and I used my brand new credit card for the first time here and later in the day attempted to use it again and it was declined. Called my CC company and they said someone tried to make an internet purchase from the Fontana area and it was flagged. Nobody else had access to my brand new credit card except whomever I handed it to at the drive thru so...... This happened 2-19-25. Card was cancelled and reissued a new one. lesson learned.... Apple Pay or nothing from now on. Still giving 5 stars because the owners shouldn't be penalized for employees actions.

We decided to give this place a try since we were in the area. I first heard about Mr. J's through Instagram influencer Obieats and came mainly for the chili cheese fries with pastrami. At $12.99 for a large, the price was reasonable, and the three of us shared it along with some fried zucchini and cheeseburgers. The chili fries were a bit salty but generously portioned, with a massive pile of pastrami on top. The burgers were comparable to those from any typical charbroiled burger spot--nothing unique--but based on the steady flow of customers, it's clearly a local favorite. Overall, it's a solid choice if you have a big appetite and want a satisfying meal without spending too much.

I had a very good turkey burger here today, with excellent seasoned fries. The woman at the counter was very friendly and the servce was quick. There is a fast food/diner feel to the place and the pricimg was very reasonable. I would definitely come back!
