Although everything at El Salvadorian spot Bahia in Williamsburg is tasty, the real draw are the $2 pupusas. These cornmeal cakes are stuffed with cheese, beans or pork (or a combination of the three) and griddled to perfection. For the best pupusa experience, make sure to top each one off with a generous helping of cabbage and hot sauce. Hot, tangy, filling--these culinary delights are among the best bargains in Brooklyn.
