The thick, juicy half-pound patty is made from prime-rib meat and sits on a lightly toasted ciabatta roll that can handle the heft.
Ours was topped with avocado, bacon, pepper-jack cheese and sauteed mushrooms, with a mound of crisp, well-seasoned fries ($11.95). Best strategy: Cut the monster into halves.

Tip: Sit at the bar for this meal; it's the best seat for people-watching and to overhear the inside chatter between the bartenders and the serviers.
