The Standard, High Line
Three great options.
The Standard Grill for eating a BLT or burger. Their fries are extremely crispy even cold!
The Standard Biergarten: the original 1st version New York's Octoberfest all year round. Purchase your drink tickets for your beers and order a pretzel or grilled sausage.
Le Bain, on the roof top, is one of the most chill bar of NYC. We remember a birthday party where we ended up in the hot tub in boxers a memorable Sunday night! Yes, they have an indoor and outdoor Jacuzzi. And of course, they will lend you bath towels.
