Are there any cheap restaurants in the centre that I can try?
Yes, there are many. What type of cuisine are you interested in?
can you suggest one, I am not picky, just need the type and address
Sure!  The Golden House is a Chinese restaurant that's located at 12 Lensfield Road, City Centre.  Would you like a table reserved?
No thank you.  I need to find a train leaving Cambridge after 16:30.
I have 5 different trains leaving Cambridge on Friday evening, which destination do you prefer: kings cross or liverpool street?
I actually need to go to stevenage.
What day do you need to leave?
I would like to leave on Tuesday, please.
There are trains leaving Cambridge every two hours starting at 17:21 and arriving in Stevanage one hour later. Which time do you prefer?
17:21 sounds fine. Please make a booking for 1 person and let me know the reference number.
