We were there in August and my DD6 did the BBB experience. I wouldn't rate the café - very slow service, pricey food for what it is and café on the day we were there was very very loud. The BBB was amazing however - she has done this in MK and the Harrods one was so much better and more personalised IMO. We had the first slot of the day which I would really recommend as she was first in the salon and when she was "performing the magic" it seemed more real.
