The Burrito Box is easy to miss -- it's a tiny little place on 9th Ave, near 58th St. But once you discover it, you'll be hooked. Not only do they make a killer salsa (available in unlimited portions), but they offer a variety of alternatives to traditional Mexican fare for the health-conscious (soy dairy products, endless substitutions for people who are avoiding carbs, etc.). Whether you choose the healthy route or opt for the original cheese and carboholic versions, their menu has something for everyone. It's cheap, delicious, and not to be missed. Excellent burritos.
