Can you recommend some attractions to go to on the west side of town?  
Sure thing!  We have 13 attractions that you may like.  Do you have anything in particular in mind?
No. Just pick something and give me the address. 
Okay. I recommend Churchill College at Storey's Way. Their postcode is cb30ds and their admission is free.
Okay, thanks.  I also need a train leaving on Sunday going to Bishops Stortford.
