National Fish Taco Day is celebrated every January 25, primarily in the United States. This food holiday was established by Rubio’s Coastal Grill in 2018 to commemorate the 35th anniversary of its first restaurant, which opened in 1983 in San Diego. The day encourages people to indulge in fish tacos, a dish that originated in Baja California, consisting of a tortilla filled with fried or grilled fish, cabbage or lettuce, pico de gallo, and a citrus or mayonnaise sauce. Ralph Rubio, the founder of Rubio’s, is credited with popularizing fish tacos in the U.S. after discovering them during a spring break trip. On this day, Rubio’s often offers promotions, and people are encouraged to enjoy fish tacos at various Mexican or Tex-Mex restaurants, make their own at home, or share recipes online using hashtags like #NationalFishTacoDay.
