On-demand delivery app Postmates released Wednesday what it's tongue-in-cheekishly calling the national "burrito index," and according to their burrito data, Tampa just barely slipped in to the top-30-most-burrito-loving cities in the country this year.

They put their ranking of America's Top 30 Burrito-Loving U.S. Cities together by looking at data on the total number of burrito deliveries, frequency of those deliveries and "overall preference for burritos over other foods," a news release said.

Los Angeles, Chicago and the San Francisco Bay Area were the top three in burrito-loving, with Miami at No. 6, ranking as the most burrito-loving city in Florida. Tampa ranked No. 30, just below Minneapolis and Raleigh. The company said it looked at 50 cities total.

There's a trend toward these sorts of city rankings these days, and what it really means that Tampa has been ranked No. 30 in burrito-loving, or No. 19 in football fandom, or No. 7 in Oktoberfest celebrations or No. 3 in foodies or No. 1 in being sweaty is debatable.

All that aside, Postmates said it plans to give away 10,000 burritos in Tampa on Friday, Cinco de Mayo, to celebrate the ranking.

That's a lot of free burritos to love.

To get a free burrito, download the Postmates app on your phone. Add a burrito from any available local or chain restaurant. Once you've placed the burrito in your cart, go to "add code" (you can find it by clicking the gear icon on the home screen) and enter CINCODEMAYO to make it free.

The code will work for the first 10,000 people who use it, Postmates said.
