Dan Marino's was open until right after Christmas 2005--since then it has been closed "for renovations." However, I never see any construction workers there, and would not count on it reopening.
TB is open, received a not-so-good review in the Orlando Sentinel.
A wine bar/cafe, "The Grape," has opened, as well. Rumor was that a "B.B King's" restaurant and "Oceainaire" [sp?], an upscale seafood restaurant, would also be coming, but haven't hears an update on those in months.
