What is at the Boardwalk now is called the ESPN Club. Which is I believe an early concept for what is now the larger ESPN Zone. The ESPN Zone is a restaurant and sports bar, with nearly every sport available on screens throughout, which also has with gaming areas (sports oriented arcade type) and gift shop. Think of a Dave & Busters themed to sporting.
There's an ESPNzone in DL, and while I think the restaurant is popular, I think its biggest draw may actually be the arcade on its upper floors. They're all sports simulators and it was packed when I was there.
