If you're going to do an afternoon tea in London then I would 100% recommend going to Fortnum & Mason tearoom (upstairs). We tried looking for cheaper options of a similar quality and there were some available, however the price difference wasn't much and so we decided to book at the best. :) Amazing food and service, we even got given what we could finish (plus some extras) to take home with us. Most likely a booking is required to avoid disappointment.
