Camberville Dancing

OK, again, I am going to try something new. As some of you may have noticed Rachel rarely posts, so this is my thing. SO-I can do whatever I like! Down to business, this is going to require responses from you readers.

Who knows of a good dancing place on Saturday nights?

*It is my birthday and I need help. Few requirements:
~I like this side of the river
~Bands are OK. (Burren for example is perfect, BUT, all of Cambridge and Somerville attempt to fit in the backroom.)
~I like top 40, classic, 80's.
~I like bars, not clubs.

Thoughts? Help!!
