This deli has the best sandwich in town - the Cubano. I've eaten every cuban sandwich you can find, including at the Havana Sandwich Shop, and the Cuban at The New Yorker Deli is not only the best Cuban in town, but the best sandwich in town. The pork is marinated in something so that it is juicy and ridiculously flavorful. In addition to the mustard, there's some other sauce that they put on the sandwich that makes it even richer and more delicious. I've literally had this sandwich 50 times, and every time it is perfectly the same. My mouth is writing just writing this.
Pros: The sanwiches cannot be beat
Cons: Seating is limited, but you can usually find somewhere to sit
