We stopped in after a concert down the street. It's hard to find something that is still serving food at 11PM but they were so we gave them a try. They only serve pizza at that hour but it was delicious. It's a little on the high end side but not stuffy (we were in concert tees and jeans and didn't feel out of place) and for as fancy as the pizza is it's not overly pricey.
We got the Pittsburgh pizza with potato and onions on it and could not have been happier. My wife got a Moscow Mule and said it was perfect.
The staff was attentive and very nice. I'd gladly come back.
