I like potbellys food and have always enjoyed it but please tell me why is there the need to have live entertainment at lunch time. The location is already noisy and then you put a live singer on top of it and you can't hear anything. I feel bad for the workers because I left there with a headache and I didn't even stay to eat. If I wanted music entertainment I would go to a club at night not at potbellys on a lunch break.
