I would have to say that Big Daddy's is one of my favorite burger places in Charlotte. The food is very good quality and always cooked to perfection. I have eaten here dozens of times and have not once had a dry or tasteless meal.
The menu itself has a variety of burgers to choose from including the southerner burger which has coleslaw and chili (my current favorite), and the Mama Ricotta's burger which is a true tribute to the restaurant that it was named after. That said, my true favorite (the burger with Guinness beer battered onion rings) was taken off of the menu. *sniff, sniff* You are missed dear burger!
The menu does have an assortment of chopped salads for all those meatless types, and there is a pretty decent beer selection too to wash everything down. Although, I have yet to find a beer that goes well with salad.
One thing to keep in mind when you go here... if you are going on a Friday, Saturday, or Sunday, or any other time when people eat, be prepared to wait a little while. This place is always hopping!
