In the winter months, Brooklyn’s Smorgasburg can count as a food court, as it’s held indoors. Come spring, the 100 or so food vendors that make up this lollapalooza of munching take their stands outdoors to both East River State Park in Williamsburg on Saturdays (enter at Kent Street and North 7th Street) and to Prospect Park on Sundays (Breeze Hill, East Drive at Lincoln Rd. is the entrance you should use).
As for what you’ll eat here, the question might better be put “what won’t you eat?” The variety of foods is staggering and the quality incredibly high. On a recent visit, my group noshed on curried hot dogs with a slaw of kimchee apples; oysters with three delightful mignonette sauces; fried eggplant with yogurt sauce; root beer–flavored macaroons; fab barbecue; and El Salvadorean pupusas (like a tortilla, with a variety of stuffings). If you're looking for something to take home with you, I highly recommend the artisinal horseradish, an excellent condiment (and a great gift).
