We would like to attend an event at the theatre while we are in town. 
That sounds like fun. I've found five theaters in town. Four of them in the center of town, one to the south. Do you have any other criteria? 
Nope, choose the one you think is best and let me know the postcode please.
The adc theatre is very good would you like that one?
That sounds great! Can I get the postcode? And then I need to find a train.
The postcode is cb58as. What day and time will you be travelling on? 
I am going to stevenage on thursday.
Where will you be leaving from?
