We really like Boma at AKL. If you do it, make sure to go early and see the animals, look for hidden Mickeys and visit the gift shop.
We eat a lot of our meals in World Showcase at Epcot. Marrakesh in Morroco is probably my favorite, but I also would recommend San Angel, Chefs de France, Teppanyaki, Akershus and Le Cellier.
We also pretty much never go to WDW without eating at Prime Time Cafe and Mama Melrose in MGM. We have older kids, so we send them to Pizza Planet while we eat at Mama's -- works out great!
