The Taco Bell in Clarion is one of the nicer Taco Bell establishments that I have been too. The dining room is a little on the small side, but it is clean and the condiments are always well stocked. The drive through is a little bit of a tight squeeze if you have a bigger vehicle, but the service is usually pretty fast.
The deals that they are offer are pretty good and the food is always wonderful. I really like that you can get both hard and soft tacos with the meals and don't have to choose one of the other.
I can't say enough good things about Taco Bell.
