Just my opinion but anybody with cut squid, a good bottom rig and the right drift can catch fish just about anyplace in the Bay. Thats what makes it some unique/fun to fish.
The CBBT is of course one of the best spots because it is a huge structure and holds almost every species you could imagine, however, don't forget about the following structures inside the bay. Fish listed are from fishing reports off this board or from my limited experience:
HRBT. Flounder, Specs, Spot, Striper, Croaker and I read a report today that someone caught a cobia there and spades at the Rock islands.
MMBT. Flounder, Specs, Spot, Striper, Croaker and there are a few reports of Spades from thier rock islands.
James River Bridge. Spot, Striper, Croaker and just up river you can catch Catfish.
Thimble Shoals light house. Flounder, Specs, Spot, Striper, Croaker, Cobia, Spades and sharks.
ODU Reef. Flounder, Spot, Croaker, Cobia, and sharks.
Channel ledges/Bouys. Flounder, Spot, Croaker, Cobia, Striper and sharks.
Go ahead and use google to find/locate these structures and the ramps or get a ADC map (I recommend both). Pay attention to the reports on this page and have a ball. I know I have for the last 2 and half years since selling my bass boat.
