#1: O'Neill's Irish Pub
#1: O'Neill's Irish PubAs New York City's longest running venue of traditional Irish music, it's no surprise that O'Neill's Irish Pub was the most sought-for bar on the one day a year when everyone's craving something Celtic. Enjoy the "seisiun" (basically the Gaelic word for "jam sesh") and try not to trip while drunkenly attempting that Irish step dance. O'Neill's Irish Pub 729 3rd Ave New York, NY 10017 [Photo via]
