Sunday, August 10th, 3:00PM-7:00PM at St. Nicholas Park and 135th Street. DJ Stormin Normin brings back the festive dance party in the park that brings all of Harlem together. This free family friendly event is one of the better ways to have a Sunday picnic uptown and almost everyone shows up at St. Nicholas Park for this event. There's a great mix of people of all backgrounds and Sundae Sermon always serves up some great people watching. Sundae Sermon only happens a couple of times during the season so make sure to mark your calendars.
