Heehee! I actually worked at O'Charley's for a few months when it opened here. I actually like the food, but I also customize like crazy when I order. I have noticed that prices range depending on the location. The middle of Virginia isn't exactly as expensive as DC.
If I had to pay more, than I probably wouldn't like it nearly as much.
Overrated in Chicago is the Billy Goat Tavern. Yes, I realize it's nostalgic and a landmark to the city, but the food...ehhh.
