A zebra dome is a small dessert, looks kind of like a white chocolate truffle candy. It has a mousse-like filling, tastes like coffee-flavored. They're good, but I don't see all the hype they get.
I know they have them at Boma dinner, but not sure if they serve them at breakfast. They also sell them at The Mara (AKL's CS place), but not sure if they are available in the morning during breakfast.
