Tap-dance studio by day, speakeasy by night, Harlem Tap has been described by owner Omar Edwards as an "interval hang." By that lovely turn of phrase, he means that the pint-size West Harlem spot is not a full-on destination club, but a place where you chill and have a drink for maybe 20 minutes or a half-hour before moving on to the spot where you'll actually spend your Saturday night. Founded in 2006 by two of Broadway's tap luminaries, Omar Edwards (Bring in 'Da Noise, Bring in 'Da Funk) and Dormeshia Sumbry-Edwards (who choreographed the Spike Lee classic Bamboozled), the studio offers classes for all ages during the week. On weekend nights, dancers from around the neighborhood roll in at all hours to grace a stage just big enough for one with impromptu performances. Some of them are damn good. And it's right next door to St. Nick's Pub, the oldest continuously operating jazz club in Harlem, which has a hoppin' Africa night on Saturdays.
