To qualify, I have technically only had one cocktail here, but was very satisfied with the experience.  Of course, I got to try sips of all the others at the table, which gave me more data on the cocktail quality beyond my one drink.  :)  I had the Immortality juice, which sounded light and refreshing but was boozier than expected.  Very tasty and balanced, however.  They seem to make things on the tarter side, which suits my taste just fine.  All the others I tasted were similarly well balanced.  The place has that prohibition-era feel to it, which by now is nothing new, but it is beautiful and cozy inside.  Service was very friendly and prompt.  I would definitely go back anytime when I'm in town!  Good to see Pittsburgh getting some great cocktail places!  I would love to try the food too...
