I just learned Rules has discontinued their Afternoon Tea service. Sob.
They call their afternoon tea, a Royal Afternoon Tea, and it certainly made me feel like a queen. First class service from a uniformed waiter, beautiful plush surroundings, fresh flowers everywhere (even the loo) superb food and delicious tea.. The price was 32.50 GPB which seemed a bargain in comparison to other places offering similar menus. It's at 35 Maiden Lane, Covent Garden so is very handy for sightseeing. I only splurged on a special afternoon tea once on my trip and I'm glad it was at Rules restaurant.
