The "Big Dog Daddy" Burger

Why it’s extreme: As part of the Bar & Grill’s 100-ounce, “Big Dog Daddy” challenge, this burger will leave you more than full. And, if you finish everything in the challenge (beer, fries and all) you get a T-shirt. This massive burger (yes, it’s actually the size of a plate) contains a two pound beef patty, 4 ounces of cheese, 4 ounces of lettuce, tomato and onion, 2 ounces of pickle and a 10-ounce bun. The burger is served with a 32-ounce beer and 16 ounces of “freedom fries.”
