Can you give me information about local parks I can visit while I am in Cambridge?
May I suggest the Cambridge University Botanic Gardens?
What part of town is that in? I'd like to stick to the east side, if possible.
No, it's not.  But we do have a terrific park in the east side.  It's the Cherry Hinton Water Play Park.  Would you like the address?  
Yes, along with the postcode and entrance fee please.
