Went with LogdeC a while ago and enjoyed it very much.
We went to a bar near Congreso that evening. I think it was on the corner of Bartolomé Mitre and Rodriguez Peña.
The waitress ignored him at least three times after she took his order, we made two trips to the bar trying to get his beer and eventually, half an hour later, the libations arrived.
The show was very funny.
Few natives, mostly gringos. You should enjoy it and possibly make new acquantances.
