I am looking for a train going to stevenage and departing from cambridge.
There are 70 trains, what day and time would you like to go?
I would like to arrive by 17:00 on Monday.
There are 6 trains available. What time would you like to depart?
Departure time doesn't matter, I just want to arrive by 17:00 Monday. 
In that case, the TR2045 may be the train you want. It pulls into stevenage at 16:10.
Okay, book it for 8 people and get me the reference number. I'm also looking for a college in the south.
I was able to book the train for you. The reference number is NVL339KD. 
I am also interested in visiting some colleges on the southern tip of town. Can you help me find those?
I'm sorry but I don't have any colleges listed in the south. I have plenty in the city center. Would you like to try a different venue or attraction type?
Yes, an entertainment venue would be great. Please give me an address to one you find. 
Nusha is an entertainment venue in the south. The address is unit g6m cambridge leisure park, clifton road.
Okay. Thank you very much that is all I need.
Thank you and have a safe trip.
