We had booked to have afternoon tea at The Shard. The actual tea itself was good quality and enjoyable......although tea was cold when we eventually got to it. The experience was for 2 people and we had booked 2 tickets for the 4 people going. On arrival we were told that one of the voucher codes couldn't be redeemed as it had been cancelled!! I ended up having to go through emails to prove it was correct and had not been cancelled then forward the email to the restaurant supervisor. I cannot fault the staff they were very professional and helpful but all 4 us felt very embarrassed especially in such a high class establishment. It also took the shine off the day which was purchased as a xmas present for my mum and a present for my 40th birthday.
