USA TODAY - When you close your eyes and picture a perfect taco, what do you see? Is it the Ortega taco-night special: a hard-shell taco, spiced ground beef, shredded cheese, lettuce, and tomato?

There are plenty of tacos out there, from fried fish to pork with pineapple, and from roasted goat to cow's tongue, and The Daily Meal set out to find America's best.
