In PA as long as you are out by 9pm and not sitting at the bar or high tops you are good there. I've seen kids there plenty before 9pm - even very young kids**. **They do not accommodate toddlers and babies. They weren't happy & refused service when my brother & sister-in-law brought their toddler and tried to eat their with my parents. So I'd say over 5/6 years old is cool
We have taken our 17 and 19 yo in for the burgers at a normal dinner time. I don't see a problem with it.
