S: I can help!  What kind of food are you looking for?

U: Still deciding, can I set up a train ride first?  If would be from londons kings cross to cambridge, on saturday leaving after 11:00AM.

S: The TR7309 leaves after 11:00. If you'd like to make a booking, I'll need to know how many tickets you'd like.

U: I need 4 tickets. How much will that be?

S: The tickets are each 18.88 so 75.52 in total

U: Ok. Can you complete the booking for 4 people and then give me the reference number?

S: I was able to book you. Your reference number is H9AGMLJM.

U: Yes, I would like to find a place to eat. Please find me a moderately priced restaurant in the centre.

S: there are quite a few moderately priced restaurants in the city centre. do you have a preference on cuisine?

U: Nothing specific, anything in the centre is fine.

S: May I recommend the very popular Efes restaurant serving turkish food in the centre of town in the moderate price range.

U: Is there a nice view from the restaurant?
S: Past customers don't agree on the quality of the view from Efes restaurant. It has been called splendid, but also described as not the best.
