What trains will leave from cambrige and arrive by 13:00?
Well, that depends on where you're going and the day you're traveling. Do you have that information?
I need to get your London Kings Cross on Saturday.
There are four trains that meet those criteria. They leave at 5, 7, 9, and 11 and arrive 51 minutes after departure. Would you like me to book one for you?
What is the train id of the one arriving closest to 13:00?
TR5170 is arriving by 11:51, that is the closest time to 13:00 that is showing available. Would you like to book a ticket?
Yes.  I am also looking for a Vietnamese restaurant in the centre
How many will be traveling?
Only me so so just one
I have you booked on TR5170 with reference number KH6HKQ4X. Unfortunately, I have no Vietnamese restaurants in the centre. Would you like to try another type of food or area?
Ok, how about an expensive british restaurant?
In British restaurants you have three choices: Fitzbillies, the Midsummer House, and the Cambridge Chop House.
Could you please send me the address, postcode and phone for the Midsummer House?
The address for the midsummer house restaurant is Midsummer Common, the post code is cb41ha and their phone number is 01223369299. Would you like me to book a reservation?
No, thank you. I can book it later. I think thats all I need for today. Thanks. 
So happy I could help you today. Thank you for using the Cambridge Towninfo centre. Have a great day!
