Whenever I come to Pittsburgh to visit friends & family, I always make sure to make a stop at Z:Lounge.
Great music, people & atmosphere.
They also have a fabulous selection of beers (they carry my fave Lambic!) and you must try a martini or cocktail as their bartender, Ova, was recently awarded "Best Bartender" from Pittsburgh's City Paper!
Definitely drop in if you're perusing the South Side!
