There is not much to say about this place that has not yet been said, so I will just note that I went here twice in one day for $3 cheese pizza and it was excellent. I would go three times in one day if I could. My friends from out of town (Texas and England) seemed to want to eat non-pizza food, though. I don't know what's wrong with them.
The only downside is the serious lack of seating (six seats) but the Cosmopolitan has seating EVERYWHERE. We had drinks in the Chandelier beforehand, which I highly recommend.
