This Tijuana-inspired taco stand, which previously did business as Tacos Mariachi, in Trinity Groves, serves a seafood-heavy menu of tacos, but the costra de salmon — smoked salmon wrapped and toasted in asadero cheese — is a show-stopper. Someone should put one in a vault to be preserved. It's Dallas' Luka of tacos. Also try the mole fries topped with crema fresca and carne asada. Or put a big pink heart on every Wednesday on your wall calendar to remind you of the Wednesday brisket taco special, a carryover from the original location that was finally revived this summer.
