Dancing

I am looking for a club, ballroom, or bar with a dance floor that would be open Sunday, Monday, or Tuesday evening.

I am pretty open on the type of dancing: County/Two-Step, Latin/Salsa, Partner/Ballroom or any combination of the above. Ideally a friendly place open to inviting strangers to dance since I'll be on my own. I'm not really a fan of line dances or freestyle.

Places with lessons are always nice, but I have enough experience that it is not necessary.

Any recommendations?
