Info I found from very old Websites:

#3-DAVID COPPERFIELD has joined forces with LateNite Magic, Inc. and plans to open "David Copperfield's Magic Underground." The 20,000 square foot underground food and entertainment complex is located in Times Square.
Plans are also underway for a second "Magic Underground" at the Lake Buena Vista, Florida "Walt Disney World Resort". The restaurant's food and service is designed by Joe Baum and magical setting created by David Rockwell. David says it will not be a themed restaurant, but rather more of an interactive entertainment experience from which you won't want to escape. On the other hand, it will have secret tunnels through which he can appear and vanish.
David Copperfield's Magic Underground in New York was scheduled to jump out of the creative hat around the end of the year. However, building work has stopped. Massive cost overruns used up the $26 million budget. Originally projected to cost $20 million, now estimates have increased to more than $30 million.
On Dec. 30th the New York Post reported that "...investors stand to lose the $30 million they sunk into magic-themed restaurant of David Copperfield, which may never open." Similar stories about the restaurant have been reported in other papers and magazines as the theme-restaurant business is beginning to soften

#6-Copperfield's Delayed
Copperfield Magic Underground, magic themed resturants set for New York and the Disney/MGM Studios Theme Park in Orlando, have been delayed by cost overruns and technical problems. The Orlando restaurant is now expected to open at least three to six months later than first planned. (9/18/98)
There are many more websites like the ones above. Also, I was very bummed out when I heard this was cancelled. I am a huge, HUGE David Copperfield fan.
