Mr. J's Char Burgers

Mr. J's Char Burgers is a no-frills spot along Foothill Blvd in Fontana where the focus is squarely on generous portions and a diverse menu that stretches beyond just burgers. This is the kind of place that fits comfortably into the rhythm of a local’s day — whether you're stopping by for a quick breakfast, grabbing lunch, or winding down with some classic fast food dinner options.

The atmosphere here leans casual and straightforward, with a friendly staff that seems accustomed to handling everything from busy drive-thru lines to pickier eaters without missing a beat. It’s not a fancy sit-down destination, but it feels like a community joint where large families and groups of friends can get hearty meals without fuss.

What stands out most are the sizeable plates delivered at a steady pace — customers often come away talking about the “enormous” portions. For those who like to mix things up, the menu offers more than burgers: think grilled chicken and gyro sandwiches, pastrami burritos, and even salads that provide a lighter counterpoint. The BBQ Onion Ring Burger and Chili Cheese Fries get regular nods, appealing to those who appreciate classic comfort food with a little extra kick.

Breakfast options are also on hand, making this a breakfast-through-dinner spot. On busy weekday mornings or weekend afternoons, expect a steady flow of orders, including people grabbing a quick Chicken Gyro or a classic Club Sandwich with fries. Drive-thru lines can get long during peak hours, so timing a visit for mid-morning or early afternoon might make for a smoother experience.

Overall, Mr. J's feels like a place locals return to for filling meals that hit the spot without pretense. Whether you’re craving a straightforward bacon avocado cheeseburger special or want to tackle the infamous pastrami challenge, there’s an honest portion of solid fast food waiting. If you’re passing through Fontana and want a reliable, bustling spot with hearty offerings, this is a practical, no-nonsense option.
