Century Ballroom:
Splendid place to go, whatever your skill level may be. Take a break, watch the advanced dancers, and steal a new move! Hallie Kuperman runs a fine ship, offering a friendly place for people of all ages, backgrounds and sexual preferences (featuring an "Out Dancing" evening weekly). The dance floor is large, the setting historic and plush, yet funky, too. And the price is right: $6 for the practicas, $10-15 for Saturday dances (with or without the lesson).
On their web site, you'll find weekly salsa, swing / Lindy, lessons, special events, a tasty cafe, and new arts endeavors in the making:
