Charley's Grilled Subs - Feedback

This is my favorite place to eat at the airport nowI ordered small Philly cheesesteak and it was good.

I've never been to a Charley's before so I thought it would be a more unique option than the Burger King, Taco Bell, and other familiar chains.

Whenever you see a group of construction workers eating at the same place, it's usually a good indication about the quality of the food.
