At the time I didn't really think my burger (buffalo, with grilled peppers, zucchini, and mushrooms) was worth the $20 it cost, but I did find myself dreaming about it later that night. It's not often that I dream about food, so I figure this alone warrants a 4* rating.
(One thing, though: I don't understand why, if buffalo is supposed to be as ultra-lean as it's advertised to be on the menu, my burger appeared to be oozing a fair bit of grease...)
