I have been to the Burger Bar a few times and the food has always been good. However, today I was sorely disappointed. The food was OK, but the thing that turned me off today was the lack of cleanliness. Lots of caked up grease on the grill, flies buzzing around an open trashcan, a counter-top material that can't be cleaned very well, folks handling raw food with bare hands, etc. etc. I don't know if they're required in Bristol, VA, but nobody working at the grill had on hairnets, or rubber gloves - they hardly even had on aprons.
They even cleaned out rolls or biscuits from a warmer into a plastic bag and gave them to a customer who was leaving. Sorry to have to say it, but I won't be back..
