Taco Bell has tried to enter the Mexican market twice, failing both times, even after branding their food "American" food.

Taco Bell is nothing like real Mexican food, which is delicious. Mexicans don’t use ground beef in any of their tacos except one called picadillo and they rarely use chicken. 

Neither is there any such thing as a hard taco shell. The closest thing to a hard taco shell is called a tostada and it is flat and orange and often served with a layer of beans and cheese on it. It isn’t shocking that Taco Bell is a total flop in Mexico. 

They’ve tried t enter the market twice and bombed twice. Other American fast food chains that are popular are McDonalds, Dominos Pizza, and Carls Jr. Starbucks is HUGE in Mexico and Krispy Kreme is on the rise. 

Taco Bell was founded in 1962 in California by Glen Bell. By 1967 they had opened their 100th store. They tried to plant themselves in Australia in 1981. A few stores opened, but by 2005 the Taco Bell brand was yanked from the country. In 1981 they also began planting themselves in Canada. However, their Canadian owner, Priszm, went bankrupt in 2011 and the stores folded.
