(London’s revolving restaurant in the BT skyscraper, previously known as the Post Office Tower was supposed to reopen by 2012 in time for the Olympics. Unfortunately it doesn’t look as if it is going to happen now. In fact, it has not been an eatery since 1980 when the the Top of the Tower venue, which was run by the Butlins companys (I kid you not) closed after 14 years. It was shut amid security fears after an IRA bomb exploded in the gents lavatories in 1971. Still if you can’t wait to try eating on the move there is a list of the best revolving restaurants here: http://travel.yahoo.com/p-interests-40766329.)
Over the past 50 years, revolving restaurants have opened in more than 50 countries on six continents, from Colombia to Nepal to Canada.
