If you prefer to book your afternoon tea rather than queue with the masses outside Bettys, York you could always book a table in the Belmont Room (just upstairs via a ‘less obvious’ doorway). Available Saturdays and Sundays from 1-6 pm, afternoon tea is the only option. The art deco design is a fantastic complement to the great food and service.
