Have lunch at the Tea Terrace on the roof of House of Fraser in Guildford 

The Tea Terrace serves afternoon tea and lunches with brilliant views of Guildford. There is a large modern indoor seating area and a outdoor area complete with a mini lake  and impressive shrubbery. The Tea Terrace gets very busy especially on a Saturday afternoon so probably best to avoid key times if you want the best service. For us on a sunny day the outside terrace would be perfect. Having afternoon tea overlooking the Surrey Hills would take some beating.
