- SSsimplemountainsJan 29, 20261.0Did mobile orders multiple times here to give them a chance, but they ALWAYS get orders wrong no matter who’s on shift. One time they gave me a crunch wrap and burrito with NO MEAT and forgot BOTH my drinks! Insane!!! Go to any other Taco Bell and definitely not this one!
