Visited DC last weekend and went to Oyamel for the first time. I'll give props for the beef tongue taco and cabrito taco, but everything I tried was very salty, and in some cases inedibly so---the grasshopper taco in the latter case. (And I'm no salt-phobe and can't stand underseasoned food.) I know lots of Mexican food is inherently salty (chips, cheese, etc.), but even the salsa and guac were dominated by salt. I also found the prices too high relative to portion size, and the classic margarita really average and too light on the tequila.
