Regular bar, which is fine. However, for whatever weird reason, terrible and occasionally hilarious things seem to happen to me there. For example, I once lost my cell phone in a snowpile right outside. I once drunkenly agreed to a $50 challenge to drink a shot of our table's spillage. I once was almost beat up as my drinking buddy saw a girl he thought was an ex (she wasn't), kissed her and shouted "Nobody Leaves Chris Lastnamehere" repeatedly. (Interestingly enough, the non-ex ended up leaving with my friend and eventually became a real ex.)
So, when I'm back in town or talking to a friend that still lives there, and Killarney's is mentioned, I get a shudder. I don't know that I have the intestinal fortitude -- and certainly not the tolerance level -- to pull off any more nights there.
