The impression I got from getting there, because I was stopped by someone who told me it was full, was that there were two, it's the Why Not on the left, the Magoo's I could not remember very well seeing inside.  You enter the passage and on your left, on the left was Why Not, on the right was Magoo's.  I didn't look into Magoo's at all.  I found out later that it's where they play live music, but at that stage I don't recall being able to see in there.
