Restaurants come and go in the Lower East Side, but Barrio Chino has held its own for a while now, dishing up reasonably priced Mexican fare and oh-so tasty margaritas. The best one available is the ridiculously spicy—but still smooth—habanero grapefruit. The chile peppers are infused in Sauza Hornitos reposado tequila, which is then combined with fresh grapefruit juice, served up on the rocks. Slightly tart, floral, and packing a lot of heat, this is by far our favorite 'rita in the city. Come prepared with antacids—you're gonna need them. 253 Broome Street, 212-228-6710, barriochinonyc.com (10002)
