We visited Nox's Tavern late last night for dinner. Even at the late hour, our service was awesome, and the staff were very friendly. I tried the Smashing Pumpkin cocktail, which was delicious, on special, and looked amazing. For a neighborhood bar, they have a nice list of tasty cocktails.
The food was also awesome. They make steamed burgers. I had ever tried one before, and I don't think you can find that technique at many restaurants in Pittsburgh. Overall, it is a low key bar with great, unique food and drink with competitive prices. Definitely check it out!
