Staggering into the dimly opulent interior of The Grill Room at the Cafè Royal from the windchilled, damp and sale-blasted trauma of Regent Street delivers something of a mini culture shock. Here, all is calm and serene. It's truly gorgeous in the old fashioned sense of the word: a windowless room draped in heavy, carnal-looking red, decked with gilt, twinkling mirrors and stately carvings. Garlands, oil-painted panels, etched glass and mermaid-like art nouveau maidens crowd every nook and cranny. Staff are quietly formal, taking on an air of being lofty retainers rather than jobbing waiters. It's the sort of place you want to come on a winter's day, wrapped in furs, looking mysterious, for an assignation with someone else's spouse.
