I asked the same question a couple of days ago. . . apparently it is at the Dolphin hotel. Todd English's I think. I never heard of it either. The poster told me you also get 2 hours of Camp Dolphin for the kids if you eat there.
I vote for the Coral Reef. I have been to Fulton's and The Flying Fish, but I love Coral Reef. The atmosphere is the best - floor to ceilling fish tanks, complete with sharks and an ocasssional diver. I also love the food. I once had a scallop appetizer that was to die for - expensive, but I think about those scallops often! I booked a return visit to the Reef for the end of August.
