Mushroom Steak Sandwich

$15.99

The sandwich board's headliner: griddled steak and sautéed mushrooms with melted cheese and house sauce on a toasted roll, $15.99. It's the order for the burger-adjacent mood — same griddle character, savorier profile — and it's earned a following that treats it as a destination order, not a fallback.
