Madison Square Eats is a bi-annual food festival in the Flatiron district. It's been announced that the dates for Fall 2014 will be Friday, September 5th through Friday, October 3rd, which is a few weeks earlier than in past years.
More information and a vendor list here:
The festival is set up in Worth Square, which is a little patch of land between 24th and 26th Streets where Broadway and Fifth Avenue cross. Worth Square is bordered by the Flatiron Building on the south, Madison Square Park on the east, and 200 Fifth Avenue (aka Eataly) on the west.
As always, I can't wait! :)
