Hi Jason, when you say "Dance" do you mean music you can dance to, like house or techno? or do you mean disco?
For Pop, I recommend Smiths Olde Bar:
www.smithsoldebar.comThere is also the Star Bar in "Little 5 Points" off Moreland Avenue. For Dance, if you want house or DJ type atmosphere, I'd check out Opera. It used to be called Club Eleven50 (the address is 1150 Roswell Rd.) but recently (2007-08) changed names to Opera. it's extremely popular.
