A decent place only a few miles east of the Strip, at Tropicana & Eastern. The restaurant has a double space in a shopping center.
The pupusas are well-made and tasty, just brown on the outside and soft and hot inside. I like the queso con loroco (cheese and herbs) more than the mixed one. Not nearly enough heat in the salsa and cabbage slaw. Both Carne Asada and Carne Desebrada (pulled beef) are average, but have good portions. Yes, go there for the pupusas.
Beside Salvadorean dishes, the menu also has tacos, burritos, burger with fries.
Service is competent and very friendly. Servers speak fluent English and Spanish.
