It always surprises me when people say they have never heard or been to O'Sullivans. Yes, I admit it is tucked around a corner off Washington & Wilson Boulevard but it is certainly not a bar that should be overlooked. When all else fails I always know I will be able to go to O'Sullivans and have a entertaining and enjoyable evening. It seems like every time I go there they have live music and you never have to pay a cover. (Yes, all of you standing in line at Whitlows should try walking two blocks down the street to O'Sullivans).
The vibe from this bar is typical to Murphy's in Old Town Alexandria. Not quite chain-restaurant feel, but more like a real Irish pub. Even when the place is packed, you never have to wait long in line at the bar. Guests here feel more like regulars than most bars I have been to in the area.
If you are in Clarendon and looking to avoid long lines at Whitlows, Ri Ra, or Mister Days, stop on by O'Sullivans for hot men playing guitars and a short line at the bar.
Pros: entertaining live music and never a cover
