U: I'm looking for a train from Ely to Cambridge. Do you have any?

S: Yes, there are quite a few.  Is there a day and time you would like to travel?

U: Yes, leaving on Sunday at 10:00 AM

S: The best time matching your criteria is a departure from Ely at 11:35. Will that do?

U: I'm sorry, my travel day is actually Thursday, not Sunday. I need to arrive by 14:45.

S: I have a train TR4068 leaving at 5:35 and arriving at 5:52. Would you like to make reservations?

U: Yes, please make reservations.

S: Your reference number is : MUBTUUTM. Can I help with anything else?

U: Did you book for 5 people? Is there a train that arrives closer to but before 14:45? Thanks.

S: I apologize about that. The closest I can get you there is on train TR4992 which will arrive at 13:52. Would you like me to book it for 5 people?

U: yes with reference number

S: Booking was successful, the total fee is 22 GBP payable at the station .
Reference number is : IPO23Y22. Is there anything else I can help you with?

U: I would like to find a cheap mediterranean restaurant in the centre

S: There is one matching result. It is the gardenia. Do you want me to book something there?

U: Do they have a large beer selection?
S: Some customers commented on the large variety of beer to choose from while others found it to be lacking. Would you like me to find another place with better ratings in that area?
