As part of my hen day I'm gonna go for afternoon tea

One of my BMs has investigated the following places and my favourites are the top two. Has anyone been or know people who have been to any of them?
Athenaeum Hotel (from pastries through to the full works)
The Park Lane Hotel (I’m a bit taken with the Palm court)
Browns Hotel
Fortnum and mason’s
The Four Seasons Hotel
Claridges
Lansborough Hotel
The Savoy
The Ritz
