Pinky's is one of my go-to spots to eat in Charlotte. We usually hit this place after blowing quarters on House of the Dead and pinball at Abari. The food and service is just always very good, and we've been there three times.
I would say the best thing to get is their wings; get them extra hot if you dare! I recently tried a double cheeseburger, "ding dong style". The flavor was definitely unique, but for a more filling stomach, I would recommend you get the wings and waffle fries -- they have good flavor and aren't very pricey.
It can be ultra crowded at times, but Pinky's is a really fun place to eat while in the Queen City, especially for the wings alone.
