Chaps - On Wednesday and Sunday, it’s Chaps. On Thurday, Friday and Saturday, it’s Vapor. Got that? We don’t. We find the whole thing bewildering. But the gym-friendly gay crowd that packs the place nightly doesn’t seem to mind. Wednesday is Latin night, and if you’re in the mood for a papi, bop on down. They claim to have the hottest go-go boys, which sure sounds like a challenge to us. Friday is helpfully called “Life” and draws a more mixed crowd. On Sunday, perhaps the gayest day of the week, Chaps hosts the only tea dance in Boston. So après brunch, that seems like a must.
