Greenhouse, La Sucriere and Le Moulin Fou are definitely open, yes. By April, it's possible that Skipjacks may be back open. If so, check them out for seafood. Closed in that area is Topper's by the Sea, and it will definitely not be reopening. Happy Bay has lost basically all of it's vegetation, so if you are fair skinned, make sure you bring a cover up or lots of sunscreen, as there is no shade. Pinel is back open, better than ever. Enjoy!
