Fish tacos are popular here in Texas, and a lot of different fish, as well as shrimp and octopus are sold in the Hispanic markets here.

You obviously know nothing about Mexican food beyond what you see at Taco Bell - which is to Mexican food like Panda Express is to Chinese food.

Mexico has a huge coastline so of course fish plays a big part in its cuisine.

Don't know much about food, eh?

Many Mexican cultures depending on the sea for their protein.

since parts of Mexico border oceans, I would say that yes fish play a part in Mexican cuisine.

ALL countries have different foods in different parts of the country and Mexico is no different.
