U: Yes could you provide me with the travel time and arrival time as well please?

U: If i need to change my plans, will it be possible to switch my train ticket?

S: Unfortunately you can not switch tickets, you must apply for a refund and purchase a new ticket. Is there anything else I can help you with today?

U: I'm also looking for a place to dine. The restaurant should serve gastropub food.

S: There are 4 restaurants that serve gastropub cuisine. Do you have a location and/or price preference?

U: Yes can we try the south?

S: I am sorry there are none in the South. There are 3 in the centre and 1 in the east. Will one of those area work for you?

U: How about centre?

U: Moderate price range please.

S: Perfect, there's a place called The cow pizza kitchen and bar, would you like me to book it?

U: Do they serve alcohol there
S: It's unknown whether the Cow Pizza Kitchen and Bar serves alcoholic beverages but they do offer various non-alcoholic options.
