The verdict
Go for the music, treat the food as a decent bonus. It is a small, warm room with a grand piano, and the schedule fits our dates: Monday and Tuesday are cheap, Thursday is the stronger lineup. Book a table by phone and order food, since that is the only way to reserve. Skip it Wednesday, when it is closed.
- Shows listed for Mon Oct 12, Tue Oct 13 and Thu Oct 15 on the official calendar
- Cheap covers on Mon ($12) and Tue ($15 big band, $8 late set)
- Small room, grand piano, kitchen open for dinner
