We were there for breakfast last month and it looks like it's going to stay. The buffet is set up in a separate area by the kitchen. It's done up very nicely, with a marble counter area, glass tile and some nice decor. They have quite a nice assortment of food.
You can order the buffet (it was $18.99 when we were there in early Feb.) or you can still order off the regular breakfast menu. I love their eggs benedict but they have them on the buffet so I wanted to try some other items up there and I have to say I absolutely LOVED the grits!! I was never all that crazy about grits but theirs were so yummy!
The also have Mickey waffles, french toast fritters, eggs, bacon, assorted pastries and fresh fruit, yogurt, granola, cereal, pancakes, sausage, home made biscuits and gravy and delicious hash brown potatoes. There was also bagels and smoked salmon, onion, capers and tomatoes and hard boiled eggs. (no particular order, I'm browsing at the photos I took while we were there as I jot everything down).
It's different than FRESH at the Dolphin as there they actually make to order what you want right there at the kitchen area. The Wave is a regular buffet where the food is already made. If you want your food to order then you can order something off the regular menu. But, I found the buffet to be extremely fresh. Gets a great thumbs up from me!

Here are some photos- the first is a long shot of one side of the buffet and the second is the samples I put on my plate (of course I did eat them;-) I will be reviewing this breakfast and uploading photos onto my restaurant review website soon:
