So far, at least, Rhodes Twenty Four, his new restaurant in the City, is proving a hit. Situated on the 24th floor of Tower 42, the tallest building in the City, it's almost as hard to get a table at as The Ivy. Even after you've secured a reservation, getting in is far from easy. You have to go to a counter on the first floor, hand over your details and then pass through an airport-style magnetometer. The whole procedure takes at least five minutes so you'd be well-advised to factor that in if you're meeting an important business contact.
