I am hesitant to say this as it's already busy enough and I work in Nova Place, but Federal Galley has one of the city's best happy hours. A superb tap list gets pared down to affordable prices. If that wasn't enough they stock a great bar and can make the classic cocktails I crave. Pair all that with several food options (average to good) and you have yourself a great spot.
For the tip if you see me, give me a high-five.
