3 stars just because it is an interesting concept and they have a cool interior. If i were rating strictly on the food, at best they would get 2 stars.
Service was okay, not particularly stellar. They do make you agree to the "rules" before you are allowed into the restaurant.
The milk shake was the best part of the meal, and i am not a big fan of ice cream or milkshakes in general. The burger (a single bypass with bacon) was huge, but tasteless. The onion rings were doughy and undercooked. The hot dog one of our party ordered was huge, and probably the biggest success of the meal.
We saw three individuals weigh in over 350 pounds during our meal, which was enough to make me lose my appetite. I only managed 4 bites of the burger, but got out without a spanking.
It's fun to say we've been here, but certainly won't go back, and i can only recommend it based on the kitschy idea.
