If you're looking for nutritional food, STAY AWAY. However, if you're looking for a classic 1960's southern diner/grill-type food (e.g., hot dogs, french fries, breakfast, etc.), this is a Gastonia classic.
Now, if you visit Gastonia and don't go get a Tony's milkshake, something must be wrong with you. They're not healthy but, they are huge and sweet and so totally worth a splurge. Don't expect a five-star interior/exterior.
