Mekelburg's is equal parts hipster bodega, bar and sandwich haven. I always go for the cheese counter, the babka and the late night fried chicken sandwich, which is hands down one of the best I've had in NY.
This marketplace is home to tons of amazing local restaurants, shops, and vendors— from flowers, meat and cheese, wine, and a food court downstairs. There is definitely something for you here.
You need to make a reservation for L'Artusi years in advance... or at least the week before, if you try a walk-in then ask to be seated at the bar, as always in New York that is the best seats at any of my favorites restaurants.
Going for a stroll on Atlantic Beach is a fall Sunday must. I rarely go to the New York beaches in summer because of the crowds, but standing on an empty, windy beach is a total mind soother. Make sure to take a peek at the Miami-colored Catalina Beach Club. Beaches close mid-September.
