The Picnic House by Nathalie_B
Once you've seen or maybe even visied the Litchfield Villa walk down hill back to the Park and you'll find yourself infront of the Picnic House. This place provides you with nice tabels for a picnic, restrooms and it is available for private events too. By the way, you can find there a soda vending machine as well, in case you're thirsty.
To get there take the "F" train to the 7th Avenue station.
