The French Institute/Alliance Francaise (New York) will host its fall festival, Crossing the Line, Sept. 12th to Oct. 3rd. The schedule includes so many great events (concerts, performances, shows and more) it would be impossible to list them here. The kick off is an afternoon dance party/picnic in Central Park's East Meadow tomorrow (Sept. 12), with choreographers from France presenting a new take on the bal populaire, creating short dances to be taught section by section to the public. There will be tastings of cheese, chocolate and bread...while a brigade of top chefs from both France and New York will offer up modern bento boxes. Or, bring your own picnic. This is a free, family-friendly celebration. For all the info, click HERE or call 212-355-6100.
