As part of the French Institute Alliance Francaise's Crossing the Line festival, families can enjoy this greenmarket that focuses on urban agriculture and Brooklyn food and art. Small-batch vendors, a blue-ribbon vegetable competition, art exhibitions and the Asphalt Orchestra, a 12-piece marching band, take over Bergen Street for your and your youngsters' enjoyment. Another highlight for kids: Miwa Koizumi, a Brooklynite ice cream maker, will create a new flavor inspired by the festival. All ages.
