I found out about the London Restaurant Festival today which takes place 8-13 October. One of the most exciting events is the Gourmet Odyssey. You get shipped around London in a classic routemaster bus for a three course meal with each course at a different one of London's fine dining eateries. Sounds like my idea of heaven. Only issue is that it's £135.
The official blog says that the official press launch is on 9th September and all the tickets will go on sale. Gotta find someone to go with before then.
