Our First Lady may be crusading to make restaurants healthier, but we don’t think she’d have any luck at Fatty Johnson’s. The iconoclasts over at the old Cabrito have been gaining a bit of renown, at least in our circle, for their sublimely juicy cheeseburger, and tonight they’re unrolling a double-stacked version called — what else? — the Big Johnson. Wear your stretchy pants and prepare to shell out: The monster costs $24. Oh, and side note: Between this thing and Eddie Huang’s plans to name his future child “Huge,” it’s been a great week so far for phallic food jokes.
