The accolade comes as it scored 98%, compared to the overall London rating of 75% for customer service. The mystery shopper visit showed that the teams had excelled right across the customer service spectrum leaving the visitor with a positive experience to relay to friends and a desire to re-visit. David McHattie, chief executive of the National Skills Academy for Hospitality explains: "The role of the National Skills Academy for Hospitality is to seek out the very best training, development and education programmes in hospitality, to recognise and celebrate that excellence, and to lay down the gauntlet for the whole industry to follow their lead." Adrian Furnham, professor of Psychology at University College London added: "Smiling is not just a display of happiness, smiling also increases happiness. Consequently, in hospitality and sales situations a smile from the vendor increases the possibility of the customer smiling which, in turn, increases trust and liking and subsequently a mutual sense of co-operation and helpfulness. In short, smiling doesn't just bond people together – it oils the wheels of commerce too."
