Where the jazz jams and new jazz projects come to life. A choice of beers, single malts and cocktails doesn't hurt too, at decent prices. On some nights the jam sessions have proceeded until the sun starts to shine outside.
The draft beers are good, but the gems are the exotic craft beers and the single malts collection. Ask the manager for a recommendation if you're not sure what to try. Approach the musicians in the break between sets - most are as friendly as it gets and virtually everyone knows English.
Do NOT ask for Death in the Afternoon or the Four shots of the apocalypse if you're not ready to get annihilated.
