Does Cambridge have an Indian restaurant in the Centre of town?
I have 9 indian restaurants. Do you have a price range in mind?
I need a cheap one. 
I have 3, the gandhi is a great place.  shall I book a table for you?
Yes, please. I need a reservation for 7 people at 5:15 on Sunday.
I have booked that for you, reference number is ZB89D8NC. Do you need anything else? 
I also need to book a train for my trip to Cambridge.
Where will you be departing from? And what day would you like to travel? 
I will be leaving from Birmingham New Street on Sunday. 
Would you like to specify a departure or arrival time?
I'll depart anytime as long as I can get to Cambridge by 08:30. 
Okay. How about TR8730, which would depart at 05:40 and arrive by 08:23?
Sounds good. Please, may I have the price, travel time, and departure time?
TR8730 has a fare of 60.08 GBP, the trip is 163 minutes, and it departs at 05:40. Would you like to book tickets? Or can I help you with anything else?
