Secret Underground Tunnel Base in Central London -- FOR SALE!

How cool would this be for my WWII-themed bookstore!






For a mere five million pounds, Doolittle's could by 77,00 sq. ft of tunnel in central London. The tunnels were built in WWII to serve as air-raid shelters and later housed MI6, a Cold War communications center, and a public records center.

I can totally see the business flyers:

Who's willing to donate?
