Not Prêt à Measles

Café Opera, Royal Opera Arcade

Café Opera is in the Royal Opera Arcade behind New Zealand House - a coffee-bean's throw from Trafalgar Square and the measles rash of Prêts that infects the area around the square. 

London's first arcade, completed in 1821, 'The Royal Opera Arcade was designed by John Nash and is considered to be one of his finest works.'
