The Sinclair in Harvard Square has an upscale gastropub and a major live music venue under the same roof, so you can make a whole night out of this place. The small plates are reliably great - we like the ginger lime brussels sprouts and the burrata with smoked beets - and the cocktails are always interesting. If you don’t have tickets to the show, just start buying drinks for everyone at the bar. Eventually, someone will either return your generosity with a ticket, or get too drunk to use theirs.
