The gentrified climate around Williamsburg's Grand Street L stop is palpable, but you'd never know it just a couple of blocks away at the homey Salvadorian restaurant Bahia. You're here for the pupusas, the street food synonymous with El Salvador. A corn-flour tortilla stuffed with any combination of cheese, beans, and meat, a traditional pupusa is griddled and has a crunchy, grainy exterior with a warm and melted interior. Order three and top them with the provided tomato sauce and vinegary slaw for the perfect combination of flavor and texture. While you could easily make a meal out of these cheesy discs, Bahia's speciality platters featuring beef and tilapia are also worth exploring.
