I recently visited the Five Guys at Summit Ave in Fontana and had an absolutely stellar experience. This location truly delivers on the Five Guys promise of fresh, customizable burgers and fantastic, generously portioned fries.
I ordered the Bacon Burger, fully loaded All The Way and added a few custom toppings like Jalapeño Peppers and Green Peppers for an amazing, fresh kick. The burger was perfectly cooked—incredibly juicy, hot, and piled high with toppings that were clearly fresh. The flavor combination was outstanding and definitely satisfied my burger craving!
The Little Cajun Fry was the perfect side. True to form, the bag was loaded up well beyond the cup, ensuring I had more than enough of those perfectly seasoned, crispy potato slices. The Cajun seasoning was spot on.
Beyond the food, the dining area was clean, bright, and spacious. The service was efficient, and a special shoutout to Jimmy C. who took my order—great, fast, and friendly service made the visit even better.
If you are in the Fontana area and looking for a reliably high-quality burger experience with great service, this Five Guys is the place to go.

Our burgers and fries were so delicious!!! It was a crowded Friday night with allot of people eating inside and outside as well as picking up to go orders. Everything was great and the employees pulled off getting everything out like a well oiled machine. The only negative thing I could say was the music was too loud. There was already so much noise and having the music so loud made it very chaotic feeling. The choice of music was geared more towards a 20-25 year old male, it was like hard speed rock. I feel this music isn't really suited for a place where a variety of people eat but it was really the volume, added to the already extremely busy place, that made you want to hurry and get out. Aside from that, everything was perfect!!
What is the Five Guys story/How did you guys get your name?
Five Guys began its pursuit to redefine the global burger landscape in 1986 when Jerry and Janie Murrell asked three of their sons whether they wanted to start a business or go to college. Now, three decades after our first location opened in Arlington, Va., Five Guys – a fast-casual restaurant chain named for the Murrells' five sons – serves a classic take on hamburgers, fries and milkshakes in more than 1,700 locations across 24 countries.

Is the Five Guys veggie sandwich a veggie patty?
Our veggie sandwich is not a veggie burger, but truthfully, it can be a mix of whatever you'd like. Choose any combination of our condiments and add cheese for an additional cost.
Our standard veggie is a mix of peppers, onions and mushrooms with or without cheese.
What is the best way to reheat leftover fries?
Leftover fries are excellent reheated in the oven (or Air Fryer). According to Chad Murrell, one of the Five Guys, just pop them in a 350-degree oven for about 10-15 minutes.
Also, give those leftover fries a try as hash browns, home fries, or even as the filling in an omelet.
