I find it funny how one jack-ass behind a counter ultimately links Taco John's to putting pubic hair in food... as if somehow they train their employees to do that.
At any rate, for cheap tex-mex food, I'd say Taco John's has a more flavorful food than Taco Bell. Obviously real Mexican is much, much better, but if fast food style tex-mex is what you're looking for, I'd go for Taco John's. Only time I hit Taco Bell is is when I want a double-decker and an order of breadsticks (the Pizza Hut Express/Taco Bell combo places).
Then again, haven't had either in a long, long time.
