U: I'm planning a trip to Cambridge and I'm looking for a train that leaves sunday and arrives at 5:30.

S: There are three trains that meet this criteria, two from Birmingham New Street at 22:40 and 23:40, and one from London Liverpool Street at 23:39. Which do you prefer?

U: i would like the 22:40

S: Sure, that is train TR1873.  Would you like me to book some seats for you?

U: No thanks. I will book later. But can I get the price and travel time please?

S: Sure, TR1873 is 60.08 GBP per ticket and is a 163 minute journey.  Is there anything else I can do for you today?

U: Yes, I need to find a restaurant that serves indian food in the centre of town.

S: I have several options. What price range would you like?

U: Could you give me a recommendation?

S: How about The Ghandhi located at 72 Regent Street?

U: That sounds fine. Can you book me a table at 10:45 on Sunday?

S: Ok, how many people will you be dining with?

U: I only need a booking for a party of 1.

S: I am sorry that time is unavailable. Would you like to book for another day or time?

U: How about 09:45 instead?

S: I am sorry that time is unavailable as well. Would you like to book for another day or time?

U: Are the portions sizes good?
S: Yes, they load your plate up with large portion sizes at The Ghandhi. Would you like to book for another day or time?
