M burger: the double smash default.

Two smashed beef patties with cheese, two toppings, and one sauce. It is the easiest starting point for a full Chubby Chuck's burger order.

Why choose the M burger?

The M burger is the middle of the Chubby Chuck's sizing system: bigger than the single-patty S, easier than the L or XL, and still focused enough to customize with toppings and sauce.

Best use cases

Choose it when you want a classic two-patty smash burger. Add loaded fries when you want a full meal without jumping to XL. Use the toppings and sauce choices to make it sharper, hotter, or more classic.
