I'm a big fan of Taco Bell, their food is reasonably priced and is usually very quick to get, and tastes quite good.
I work just around the corner from this Taco Bell and I'm always disappointed with slowness and the sloppiness of the food preparation.
Most of the time I'll get my chicken supreme gordita, and it is just thrown in the wrapper. Their burritos always have a bunch of stuff all over the outside.
Overall I'm very disappointed with this particular Taco Bell, the food still tastes good through.
Pros: Taco Bell
Cons: Slow, sloppy preparation
