U: Hi, I am looking for a train from Ely to Cambridge.

S: Is there a particular day you are looking to leave on? I have trains departing ely to cambridge on Friday every 2 hours starting at 5:35. Other days are available.

U: I need a train that leaves on Sunday and arrives by 13:30, is this possible?

S: There are 4 such trains. Do you want to specify departure time?

U: Departure time doesn't matter, as long as I arrive by 13:30. Could you let me know the price, travel time, and train ID for a train that fits that description, please?

S: Of course. The TR9383 leaves at 5:35 and arrives at 5:52. It would cost 3.52 pounds per ticket. Does that work for you?

U: I am also looking for a moderate price restaurant in the centre.

S: There are many moderately priced restaurants in that area, did you have a cuisine style you are looking for?

U: I'm looking for a restaurant that serves Lebanese food.

S: Ali Baba is the only restaurant that meets your criteria. Would you like to reserve a table there?

U: Their Kafta better have good ratings.
S: The Ali Baba gets some great reviews on all of their food including the Kafta. Would you like to know more about them?
