We walked up to Martuni's to see what was going on. There was kind of a karaoke slash sing-along situation going on -- with a really talented piano player behind it all -- so we perched at a table and tried to take it all in.
There were a lot of show tunes, a few Disney classics, and at least two transvestites. And lots of gays. It was so fun!
The room in the back has the piano, but if you want to keep the singing in the background, you can stay at a table out front, or at the bar, and still soak up some of the ambiance.
