Dia:Beacon is a short train ride from the city in a former Nabisco box printing factory. This art foundation has 240,000 square feet of art from the 1960s to the present. Dia features the work of Sol LeWitt, Imi Knoebel, Andy Warhol, Dan Flavin, Agnes Martin, On Kawara, Bruce Nauman, and many others. I love going during the summer to enjoy the gardens surronding the building.
Perfect cocktails, chicken fat rice, and a REAL fireplace. One of the coziest spots in Greenpoint, particularly in the winter. Its "off the beaten path" location keeps out the bridge and tunnel goons, so you're likely to meet actual locals. Good for dates, solo thinking, or a small group.
