Very good. It is kinda a hole-in-the-wall, but was well worth it. The portions were big and the Mexican food was authentic. I order a wet burrito which cost $6.50. It was a monster. The biggest burrito I've ever had. And tasted very very good. Even the salsa had the correct amount of spice (usually these types of places have salsa that is too mild for my taste). I will definitely be returning when I visit Vallejo again.
