They have seafood and Thaifood, Thaifood is pretty good but expensive than Lotus, you can see this restaurant every time you go out and come back from Laguna area.
Check the photo below.
I just came back from Laguana Sheraton. The first two night we had dinner at Lotus. Some dishes are ok, some are not that good.
There are serval restuarant along the beach which offer thai food, italian food or international food. But I have not tried.
At the Laguana gate entrance, there are lots of shops and restaruant. You can have a lot of choice. But since my family have too many members, we were not that convenient to go there so had n't tried any.
