I recently went to Ambassadors at Bloomsbury for afternoon tea. The food was decent, the service was fine and the room we were seated in was nice enough. The only thing I found disappointing was the obvious lack of communication between staff. I had booked the tea online using a voucher several weeks before. I asked if my friend with a dairy intolerance could be catered for and they assured me that she could. We arrived under the impression that she would be able to have the same food as us, only without the dairy element. However, we were told on arrival that she would have to have fruit salad. Bit of a shame really - you would think they'd have something better in place. Dairy intolerance is not uncommon! Also at no point was I asked to bring the voucher with me on the day. However, we were asked several times to show it to staff on arrival. They ended up having to take photos of the confirmation emails on our phones. Otherwise, the tea was fine, as I've said.
