The new restaurant, as yet un-named and due to open in October 2010, will also have a retail outlet in the One New Change developement. The building enjoys views of St Paul's Cathedral and will benefit from an estimated seven million city workers and tourists visiting the area each year. Commenting on the letting, David Atcherley Symes, retail manager for Land Securities London Portfolio, said: "This is absolutely fantastic news. Jamie and Adam's fabulous new restaurant concept is exactly what we're looking for at One New Change. "The combination of what I know will be incredible food and our awesome location will mean visitors will have the most exquisite dining experience. This really sets the tone of what One New Change will offer and how exciting a place it will be." Kevin Bacon, managing director, International Restaurants for Jamie Oliver added: "Where else would we launch an innovative restaurant concept? The heart of London is the place to be and One New Change, as a new signature building set so close to St Paul's, is just perfect. Introducing this brand new dining concept in such a prominent global position is something we are extremely excited about." Oliver already has a string of successful restaurants including Fifteen and Jamie's Italian, which recently made waves in the 2010 Harden's guide. Adam Perry-Lang is an internationally recognised chef and runs Daisy May's BBQ USA in New York. Visitors to One New Change will also be able to sample eight other restaurants.
