Radisson Blu Hotel

With interiors by German designer Yasmine Mahmoudieh, the 427 rooms here are fresh, uncluttered and free of chain-hotel blandness. The Radisson's claim to fame, however, is 'the tank' - a 25m- (82ft)- high aquarium with a million litres of salt water housing 2,500 varieties of fish that dominates the hotel's atrium. Many of the bedrooms have a view of it.
