Get off the tourist track and experience under-the-radar jazz in Harlem

If you’re in Sugar Hill after 9:30 pm, drop by St. Nick’s Jazz Pub (http://www.stnicksjazzpub.net), a laid-back, tiny basement club that has been a local fixture for ages. Bring some bills to stuff into the tip jar that circulates, grab a drink, and enjoy the late-night jam sessions.
