If you are staying at the Palazzo, this is a super-convenient gourmet hamburger place right to the left on the second floor as you get off the elevator! It usually is not busy and the food is pretty good. I found myself returning multiple times during my stay.
Like any self-respecting modern hamburger place, they have several exotic burger options, as well as many different beers on tap.
Although things can get a bit pricey, they do have a great happy hour with half-price appetizers and deals on drinks (which I enjoyed on more than one occasion during my stay). If you order a large beer, you can bring the cup back later for a $5 discount on the next beer.
The receipt you get is also good for 25% off of a breakfast order - and although I didn't try it, I heard good things about it. If you are looking for something quick, easy, and pretty good, this place will hit the spot!
