Legacy is under Royale and a pretty great queer club if that's you're thing. Bijou is fine if you're into house music, the last few times I've been to Bijou the crowd was mostly freshly 21 people. The Grand is more of the same as Royale but more expensive and a stricter dress code.
Anyway, Royale is fine if you're just trying to get drunk and dance and hookup. Your post appears to be one of a number of commonly asked questions about the port city of Boston.
