Make your bubbe proud at this street fair, where local vendors pay tribute to the olden days of Jewish pushcarts. Nosh on Sephardic staples with a contemporary twist—Kossar's bialys, rugelach from Breads Bakery and bagel chips from Baz Bagel—and dance to jazz-and-klezmer tunes by Paul Shapiro's Ribs and Brisket Revue. The hangout is hosted by the Workmen's Circle, an organization dedicated to promoting social justice and Ashkenazic culture.
