Unless I'm mistaken they did the Wrestlemania press conference from there as well.
I'm sure it doesn't bother Vince all that much. Sure, it ended up going under, but in fairness most of the big themed restaurants in that style (eg. The Fashion Cafe; Planet Hollywood) bombed miserably as well.
The WWE is asking - via a quiz on their website. In specific: all members in the original incarnation, before the nWo Wolfpac/nWo Hollywood/nWo 2000 whatever - and no celeb or nWo Japan either. I got about fifteen when the time ran out. How did you do?
