Now that I've been here a couple times and sampled of the a-maz-ing cocktails, I can safely say this downtown spot is the place to impress your friends in the 'burgh.
Definitely get the chicken and waffles during brunch time. It's huge and definitely shareable. The french fries are also a winning appetizer to share. French toast is good, but a little pricey for what it is.
Service here is outstanding, especially during peak hours (which always impresses me).
Both lunch and brunch are great, but I'd definitely get a reservation for either as it's a popular spot.
