I have several options for you. The yu garden is in the east area, I can book a reservation for you, how many people will be dining?
I would like to dine in an expensive Chinese restaurant tonight I don't know. I also want to know about an attraction called Churchill College.

Churchill College is in the west and it's free to enter. Did you need any specific information about this college?
