For the record, this location is actually a KFC/Taco Bell split franchise, although you're eating the same unhealthy, chemical-laden grease food either way. Sometimes I get a craving for a beef and potato burrito and hit up a local Taco Bell, but it will never be this location again.
The employees who work here never seem to get an order correct. Between my roommate and I, we've ordered food at this location about 15 times (via drive-through). Out of those 15 drive-through visits, each order was incorrect. That's pretty bad, even for a fast food establishment staffed by teenagers/doofuses. I usually neglect to check my order before leaving, so I routinely got screwed because - let's face it - I'm not going to drive all the way back for $3 worth of fast food. And, ultimately, shame on me for being too stupid to stop coming back, anyway.
The tacos are incredibly skimpy. That is standard Taco Bell policy - to load tacos up with lettuce and the tiniest little glob of fake meat - so no surprise there, but this location somehow seems worse.
I have peered into the drive-through window while waiting for my order multiple times and have seen a bunch of teenage kids messing around with no adult supervisor in sight, so it's really no wonder things go wrong here. I'm frightened to know about food safety practices at this location when the employees can't even count to 5. For God's sake, one of the drive-through workers asked my friend if he wanted butter on his taco.
If you want Taco Bell during business hours, go to the Exton Mall which is right across the street and visit the food court. The service is much better there. If it's late and this Exton location is the nearest open KFC/Taco Bell, however, well... godspeed to you.
Update - 10/18/13
I have continued to order food at this Taco Bell despite my awful personal history with it. The accuracy has improved ten fold, so that's a plus. Ordering inside the restaurant has become as bad as the drive through used to be, however. There is usually some old retired guy (not just one in particular; Taco Bell must have hired a few) who cannot work the register. When you ask for two different things, he will have serious issues compiling the order. After 5-10 minutes of head scratching, looking around with a forlorn expression, and pushing the same button over and over, either a younger, more experienced worker will come by and help (read: ring you up) or there will be a moment of eureka and the old guy will solve the complex mystery of how to couple a medium soda with a few burritos. God, I hate this place. There is now a Taco Bell down the road where Burger King used to be, and it is soooooo much better. read more
