Picture of the owners of the restaurant shows (purportedly) that the owners are not even Mexicans........
In the DC area (I lived there for 3.5 years), I doubt if more than 10-percent of the Mexican restaurants are owned by real Mexicans....probably 80-percent are owned by gringo-Americans. There was one over in Arlington for a while that was some Salvadoran guy running it. There probably ought to be some rule....Mexican food restaurants can only be run by Mexicans....not Hondurans or Salvadorans.
