It is not just your average Taco Tuesday. October 4th is National Taco Day, and in a city known for stellar Mexican food, Los Angeles taco joints are pulling out all the stops to celebrate.

According to the National Taco Day website, Americans ate over 4.5 billion tacos last year alone. That equals about 490,000 miles of tacos, a distance that could take you to the moon and back. Those billions of tacos also weigh 775 million pounds, the same size as two Empire State Buildings. This nation full of taco-lovers has prompted a handful of restaurants in Los Angeles to hold special deals and promotions throughout the day.

The El Cholo restaurant chain will keep their happy hour prices for food and drinks from 3 to 10 p.m. tonight to celebrate the holiday. The chain has been open since 1923 and now has six locations in Southern California. One location is less than two miles away from the University of Southern California University Park campus, making it a favorite for USC students looking to chow down on Mexican food.

Chicas Tacos located on South Olive Street in Downtown Los Angeles is open for their first ever National Taco Day. This backlot taqueria will be throwing a party from 4 to 8 p.m. full of tacos and beer straight from Tijuana, according to Eater Los Angeles. With broke college students in mind, admission to the event is free.

Even food preparation and delivery service Tapingo is getting into the action. Starting at 5 p.m. tonight, the service is offering one free soft taco from Taco Bell upon delivery.

If you are willing to pay full price, there are several other taco joints near USC. El Huero and La Taquiza, both located on South Figueroa Street have that Mexican flavor you may be looking for, as does Chichen Itza on South Grand Avenue.

No matter what restaurant you choose, pick up a taco or two to support these local establishments. National Taco Day only comes once a year.
