I'm looking for a train that leaves cambridge after 20:30
Where would you like the train to take you?
I want to go to Leicester.
TR3466 leaves at 22:21 would that work for you?
Yes, that will work fine. Will you please book it for 3 people and also provide the reference number?

I'm also looking for a cheap place to dine that serves venetian food. 
I'm afraid we don't have any venetian restaurants in town. Is there something else that would work for you?
Can you recommend a place that services spanish food?
La raza is located in ctre and serves spanish food. 
Great. Thanks for all your help.
I hope you enjoy your train trip.
