Hello,
AK closes at 7pm or shortly after the park does so if you want to eat late go to DTD, but will usually have to wait. Beat the rush and eat at DTD before 6pm, last visit we didn't have to wait at all. Generally, the wait is shorter in AK, depending on what time of year you visit, but both are wonderful.
The theme is noisy, but most enjoyable the mimic a rainshower eery fifteen minutes, definatley not a quiet intimate place if that is what you are expecting.
The food however, IMHO has always been Awesome, but depends on what you are used to! I never had a bad meal there, and the service is usually pretty good, people are people and not all are meant to be wait staff

Compared to the rest of the local food in Florida, which I think leaves much to be desired, the RFC food is excellent! Mojo Bones are my favorite, next to the CObb Salad, and the rasta pasty is quite spicy.
Enjoy!
