i need a train leaving from from birmingham new street that arrives by 11:30
What time would you like to leave and what is your destination?
I want to leave to arrive by 11:30 on Tuesday and Cambridge is my destination. 
There is a bus that leaves Birmingham New Street for Cambridge at 10:40. Would you like to book it?
No thank you, but I would like the travel time for this train.
The travel time is 163 minutes. Is that sufficient?
Yes but I also would like information on finding a restaurant in the city's centre that serves Indian food.
I have 9 different options. To narrow it down some, can you tell me what price range you would prefer? 
I don't really care about the price, as long as it is in city centre. You can surprise me. I'll need a table for 8 the same day.
How about Curry Garden? What time and day would you like the reservation for?
That sounds fine. I would like it booked for 17:45 for 8 people please.
And what day would you like that table reserved?
I'd like it on Tuesday, please.
Sorry, a table isn't available at that time. Would you like to try another day or time, or perhaps another place?
Could you try an hour earlier, then?
Certainly. You now have a table for your party of 8 at the Curry Garden, at 16:45. Your reference number is V24OGNJB.
Great that's all that I need, thank you for your help today.
You're welcome. Have a nice day.
