the restaurant is actually part of the whole shark encounter exhibit.
you walk through a massive aquarium system with lion fish, barracuda, moray eels on the way to the main tank. you step onto a people mover that takes you through a plexiglass tube with the sharks and other species of fish swimming next to you and above you.
there's an outside viewing area with rays and bonnetheads outside the restaurant. inside the gift shop next to Journey to Atlantis, there's an aquarium where the floor and ceiling are glass and you can see more bonnetheads there as well.
