Please Don't Tell
You might already know about the New York hot dog. You know, that flavorless casing of meat they serve up at food carts stationed at every corner? We're not big fans of the New York hot dog here at Undiscovered New York, but we are fans of Crif Dogs, a quirky hot dog and sausage place in the East Village. The best part about Crif Dogs is that they don't just serve red hots – step inside what appears to be a simple phone booth on the side of the restaurant and prepare to enter one of New York's hidden drinking dens.

On the other side of the phone booth lies Please Don't Tell (PDT), one of the more recent additions to the city's underground "speakeasy" cocktail lounge scene. This dimly lit drinking establishment serves up high-end specialty cocktails to a small crowd of "in the know" patrons. Make sure to call ahead if you want to stop by – the tiny space fills up quickly during the evening.

Tehuitzingo Taqueria
New York in 2009 does a surprisingly good job with Mexican food. One need only look at restaurants like La Palapa and rejoice at the fact that decently good Mexican has finally made its way to the Big Apple. One of the best results of this trend towards good Mexican is the rise of the casual taqueria stands all around the city. For perhaps one of the city's more interesting taco experiences, head to the rather unexciting Midtown corner of 47th and 10th Avenue, home to Tehuitzingo Taqueria. Tucked inside the very back of a small Mexican grocery is a small taco stand, barely five feet wide, serving up some of the most delicious tacos you'll find anywhere in the city, as well as Latin-American refreshments like Jarritos and Horchata.

Burger Joint
New York's Parker Meridien Hotel along 57th Street is just what you expect: a shiny and modern upscale hotel catering to the city's more well-to-do visitors. But there's one experience you don't have to spend $500 a night on a room to enjoy – the hotel's greasy-spoon hamburger shack, Burger Joint. Walk through the marbled-tiled lobby and you'll come to a large red velvet curtain with a small neon sign. Pull back these heavy drapes and you're suddenly inside a blue-collar burger spot, complete wood-laminate walls and cheesy movie posters taped everywhere. Don't let the ambience fool you – Burger Joint serves up a delicious mouth-watering hamburger – good enough, in fact, to warrant a visit inside a fancy Midtown hotel.
