Why it's hot: Chef Enrique Olvera of Mexico City's famed Pujol made his NYC debut with Cosme, a new Mexican-inspired, shared-plates restaurant that's already so slammed, they're currently not accepting reservations until 2015. The windowless space seats 65 in the main dining room and the same amount in the bar/lounge area. Food-wise, expect Mexican flavors that utilize local, seasonal ingredients from areas like the Hudson Valley (except for a few imported Mexican veggies like beans, corn and peppers).
Must-order: The menu changes frequently but try the mushroom and squash barbacoa, lobster pibil and the duck carnitas
