While the food is mostly counter service in AK, I think it is all pretty good, and I am not the easiest person to please. We have especially liked Tuskers, by the safari. The food is good, good options for those wanting to stay more healthy, and outside just around the corner you can watch the almost constant dancing/performing that is always fun. Flame Tree BBQ is supposed to be good too. I have also hear the potstickers from the chicken shop in Asia are fantastic!
As for making a ps for akl, I don't know. I don't think there is a walk in entrance to AK for those staying at AKL. I think everyone has to ride the bus. It is close though, so I am sure it would work out. Both Boma's and Jiko are supposed to amazing.
Best wishes!
