U: I need to find a train leaving after 21:30 from Cambridge.

S: I can look that up for you! What day will you be traveling on and where is your destination point?

U: I am leaving on Saturday and going to Birmingham New Street.

S: The first train after 21:30 on Saturday is the TR5413, leaving Cambridge at 22:01. Would you like to reserve a seat on this train?

U: That'll work. How much does that cost and how long does it take to get into Birmingham new street?

S: It takes about 163 minutes and it costs 60.08 pounds. I can help you book a seat on the train whenever you're ready

U: No, I will just buy my ticket at the station.  Thanks.  Can you help me find a restaurant?

S: There are a lot to choose from. Can you give me more information to find the perfect place?

U: Is there anything in the city Centre that sells Afghan food?

S: I'm sorry but I am not finding any. Would you like me check for a different type of food?

U: Yeah, how about modern european?

S: There are 4 restaurants to choose from that serve modern european food. What price range would you rather: expensive, moderate or cheap?

U: Moderate would be fine, but any of them will do, as long as I can get in today, at 17:45.

S: I have de luca cucina and bar or riverside brasserie. Would you like reservations at one of these?

U: Does De Luca Cucina offer a high quality Riesling?
S: I don't see anything mentioning the Riesling specifically. Would you like me to try to find some information on it?
