As I was talking about last week pupusas are a Salvadorean favorite. Finding a restaurant that makes great pupusas along with other Salvadorean dishes may be difficult with a large part of the latino population being from Mexico.
When I was younger we would visit a pupuseria in San Francisco called La Costa Del Sol, which is the name of a beach in El Salvador. The restaurant that I currently go to for pupas is called El Rincon Sabroso, which is located in Mountain View. Another place I would recommend for pupusas and other antojitos Salvadorenos is Tanchitos in Eastside San Jose.
