To reiterate what other people say the Galleries lounges are pretty decent. A range of pastries, yoghurt, fruit and cereals for breakfast with breakfast rolls. A range of coffees and teas and juices and soft drinks as well as a wide range of alcoholic drinks including beer, wine and champagne.
rest of the day you’d typically get one or two hot items, a salad and afternoon tea. Biscuits, crisps and I think fruit available throughout the day.
