I wish I could dock a point here for the chips (what is this new trend of chips with burgers???) but I just can't. The milkshakes more than make up for the disappointing sides.
Burgatory is one of my favorite places to go - just make sure to get your name in 1-2 hours earlier than you actually want to eat (sometimes, when it's "slow", you can get away with a half-hour wait). The burnt almond torte milkshake is amazing - definitely the best milkshake of my life. The whipped cream is amazing, too. I have no idea what the secret ingredient is that makes it so thick and fluffy, but I think it has something to do with angel's tears.
I actually usually skip ordering a burger in favor of getting an appetizer - Just Fork It is my favorite. A milkshake + appetizer at Burgatory is more than enough food for one person. I usually walk away stuffed. Plus, frankly, skipping a burger means I'm not saddled with sad, awful chips.
