This is one of the best-themed restaurants in WDW. It is located in Disney/MGM Studios.
Like all great Disney attractions, this restaurant has a story to tell. You are treated like a guest to a big family reunion. Your waiter/waitress is your cousin, and Mom is in the back cooking. You are seated at a kitchen table with a small TV playing clips from old shows. Your waiter/waitress will nag you to clean your plate and possibly make a public spectacle of it. (Note that some people don't enjoy this interaction and find it annoying.)
The menu has home-cooking (i.e. meatloaf, pasta, etc.). The food is not outstanding, but it is decent.
This restaurant is a lot of fun for families. I highly recommend making reservations for this restaurant, as it is very popular. While you're waiting to be seated, you can enjoy a drink at Daddy's Lounge just inside.
