This particular shop has much to improve on, including its customer service. I found the young workers were also rude and inept. However, I thought their hot dogs were great.
I have not had a problem with their food (although I did not try ordering the pierogies). Their hot dogs are the best I have had. I recommend the chili and cheese or the hot dogs with everything on it. If you try this particular location in Northampton, be sure to take cash as they do not yet accept debit/credit cards.
If the service turns you off, there are other Pott's in Nazareth and in Bethlehem. I never had a problem with their service or their food. I really believe you'll prefer their hot dogs over Yacco's, Pete's, Dad's or any other competitor in the area.
Overall, Pott's is a nice alternative to the usual burger and fry fast food restaurant at fast food prices. I would recommend based on the food alone.
