Fast, fresh Mexican specialties and a signature salsa bar are the hallmarks of this restaurant chain.. In Short Founded in 1979 in Los Angeles, La Salsa has grown into a chain of quick-serve, taqueria-style restaurants. Specializing in soft-shell tacos and other Mexican favorites, the restaurant's hallmark is its salsa bar that allows customers to choose their toppings. Menu offerings include a variety of fish, meat and veggie tacos, plus burritos, quesadillas and salads. Entree-sized meal platters--like the enchilada plate or three-pepper fajita platter--come with rice, beans, chips and salsa.
