Afternoon tea in London

Lazy afternoons and tea--my two favorite things. And the English have combined these and made it an institution. So naturally when I was in London last week, I stopped by for tea. Sketch is an ultra trendy place in Mayfair--but how does this compare with an English afternoon in Dubai or Paris? Dubai--I was there in April--was most English. I don't know, it might have been the unhappy brown skinned waitstaff in full livery that reminded me of that very English place, the Viceroy's lodge in Fort William!
