How popular is Taco Bell in Mexico?

Taco Bell is not popular - at all - in Mexico. Such franchise serves food that can not be considered Mexican; From the presentation up to the ingredients, most Mexican people think of it as insipid to outright disgusting.

One example is the "taco", which Taco Bell sells on a hard corn shell, instead of a soft corn tortilla. Ingredients such as mayonnaise, lettuce and cheddar are also completely foreign to what Mexican people are used to.
