Really enjoyed this venue for a Billie Holiday tribute night. We had to wait a bit longer outside than usual (outside still being in the building I should add) but that was due to a sound issue. We were seated quickly and our drinks order was taken quite promptly as well. They had an ingenious method of using a little light to indicate if you needed to make another order without making too much of a fuss to get attention.
Smallish venue, good price, and amazing jazz-- all in the heart of Piccadilly Circus. Don't worry-- its much better in here than it is out there!
