I've just taken my holidaying mother for her birthday celebration and it was beyond perfect.
To start with when booking I was asked if there was an occasion, indeed it was a birthday so they went to the effort of presenting a pastry with a candle and the pianist played happy birthday.
The food was fresh, tasty and never ending. The staff were extremely attentive but never in your face and the hotel is stunningly beautiful. A pianist plays plesent music throughout and you can stay and enjoy the atmosphere for what seems as long as you please.
This was a highly recommendable and very plesent afternoon tea, not one thing to fault. To top the ending off as we were absolutely pached they even let us take our desired cakes home as we couldn't possible fit them in after the pastry selection.
Savoy traditional afternoon tea is indeed a must!
