Calling all fish taco lovers. Rubio’s Coastal Grill is holding its first battle for the best fish taco. Taco fans, age 18 and over, are encouraged to submit their best, original, and most delicious fish taco recipes. Finalists will come to San Diego for the chance to win $1,000 and have their taco featured on Rubio’s menu.

The window to submit online recipes, along with mouth-watering photos, is now through Feb. 27. For more information, visit rubios.com/fish-taco-battle.

The public will vote for the top three crave-worthy recipes. The three finalists will be invited to Rubio’s San Diego Test Kitchen during the week of April 17. While in San Diego, they will cook their fish tacos live for a panel of judges, including the man behind Rubio’s fish taco phenomenon, Ralph Rubio.

“It’s Rubio’s 40th anniversary, and we’re looking forward to tasting some delicious and innovative fish taco recipes from our fans,” said Rubio (left). “To this day, I remember that incredible bite of my first fish taco in San Felipe. It’s that same cravable ‘wow factor’ that we are looking for in our grand prize winner. Good luck!”

Fish taco recipe submissions should fit in with Rubio’s menu, and can include one protein of shrimp, mahi mahi, or pollock. They should feature either corn, flour, or keto tortillas, and can include any of Rubio’s ingredients plus up to three new ingredients.

The first Rubio’s restaurant was opened in 1983 at a former Orange Julius site on Mission Bay Drive in Pacific Beach and it’s still there at 4504 E. Mission Bay Drive. Since that day 40 years ago, Rubio’s has sold more than 270 million fish tacos.
