There’s a palpable sense of excitement at the Sinclair on any given Friday night. You might have an hour wait for a table of four, which is not that unusual. Walk past the downstairs restrooms, and you’re in front of a box office and not far from where a band will be playing on a stage.

The Sinclair is two venues: a music club and a restaurant. The club is already off to a strong start, booked by Bowery Boston and bringing in a variety of acts ranging from indie rock to R&B to folk. After at least a month of delays before it finally opened in mid-December, the Sinclair has already become an essential place to hear music.
