This past Saturday, people were obviously in a dancing mood at the annual Essex Street Market Block Party. The event is a co-production of the the Essex Street Market Vendor Association, the LES Partnership and the NYC Economic Development Corp. In addition to the food vendors within the market, the block party also featured local restaurants (such as Cafe Katja), activities for the kids and entertainment. City Council member Margaret Chin and Manhattan Borough President Gale Brewer joined Vendor Association President Anne Saxelby and Tim Laughlin of the LES Partnership at Saturday’s festivities.
