I was in the hotel for a 1-day course with work and lunch was provided. This was hosted in The Square which is as their website puts it is "Featuring four interactive kitchens specialising in six influential cuisines from Japan, China, India, Thailand, Europe and the Middle East,"
I selected a plateful of Roast Beef with truffle infused mashed potato and must say it was very good.
Staff pleasant, service good and no complaints.
