I'm looking for places to go in the centre of Cambridge. There are 44 different things to do in the centre of Cambridge. Can you help me narrow it down by type of activity or attraction? What's the postcode for your favorite one? My personal favorite is holy trinity church. They are on market st and the postcode is cb23nz. Anything else I can help you with today? I also need to book a train. i have plenty of trains, can i get more information please?

I've booked two tickets for the TR0523 train, and your reference number is R6GCVVA0 . Can I help you with anything else today?
