Never had an Inn-N-Out, but once when I was in West Texas I tried a Whattaburger, mainly because the name amused me. It was surprisingly good.

(Isn't there a song called "Carrot Juice is Murder"? By Russel's Shorts, or something like that? That song just came to mind.)
Arrogant Worms, and it's hilarious...

And a taco is basically spiced meat wrapped in a tortilla. Taco Bell serves Americanized Mexican food, which means it vaguely resembles actual Mexican food. Pretty decent food, though, and it's cheap. I wish I could find a place that serves Korean food. Been years since i had some good bul-gogi.
