We decided while we were at Atlantis to splurge one evening on one of the buffet restaurants and since we love seafood, we decided to try Water's Edge. We did call for a reservation, but had no problem getting one for dinner the same day we called. The buffet itself is in a lovely setting, indoors, but alongside the edge of several lagoon areas visible through large windows all around.
The real highlight here is the seafood/antipasto part of the buffet. The night we were there, it featured shrimp, several kinds of smoked fish, conch salad, crab salad (unfortunately not real crab, but the fake pollock stuff), mussels, quite a few vegetable salads, delicious grilled vegetables, and stone crab claws, mounds of them, fresh, sweet, and all-you-can-eat. That alone almost made the buffet worth the $48 per person. The entree stations were more disappointing. The steak was flavorless and mushy. The curried chicken and potatoes was nothing special. The same went for the snapper and grouper dishes. I just kept going back for stone crab and shrimp. You get a ticket when you arrive for one 6oz lobster tail per person. Additional ones cost $12 apiece. If you have a child that paid the child buffet price (I think it was about $25; children under five are free), they are entitled to a kid-sized lobster tail. It was tasty, but not worth paying money for a second. Desserts were ample and very good, especially the Key lime pie, which cost $7 a slice at the non-buffet restaurants all over Atlantis. There's ice cream for the kids, but it was a bit melted.
