Under Europe's biggest single-span roof you'll find the world's most spectacular shop window. Only the best retailers and restaurants were invited to open their doors inside Terminal 5. Each one was asked to think differently and no-one disappointed. The Paul Smith Globe store, for instance, features one-off pieces from around the world. Tiffany & Co's boutique will be the only one in Europe to display pieces from their archive. Sony will showcase new entertainment technology, often before it hits the high street. And for the first time, Gordon Ramsay brings his Michelin-starred cuisine to air travellers. Glamour has returned to flying.
