Taco and nacho?!
Answers: wats their difference?
Tacos are a hardened tortilla shell, with toppings like lettuce, meat cheese and tomatoes in the middle. Nachos are essencially the same thing, but the topping are piled onto tortilla chips instead of the shell.
Nachos are served on chips, tacos are in the tortilla.
There's not much of a difference if you're talking about the Taco Bell version of Mexican food. But if you're talking about authentic Mexican food nachos are virtually unknown to Mexico and there are as many varieties of tacos as there are Mexicans.
nachos are like doritos and tacos are filled with mince and salad etc.
