There is no charge for drinking tea in a regular tea shop. Only VIPs can enter the box. Leisure places as tired as teahouses are charged by bubble. If you want to entertain customers, you'd better buy tea in the teahouse in advance and let others make it for you.
Tea shops charge different fees, and only tea is charged for the end of a banquet. If there is a room charge, refreshments will be delivered and some tea will be reduced accordingly. Private rooms bring their own tea, booth room charge.
