I am  traveling to Cambridge and looking forward to try local restaurants.
I can help!  What kind of food are you looking for?
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.
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. 
I need 4 tickets. How much will that be?
The tickets are each 18.88 so 75.52 in total
Ok. Can you complete the booking for 4 people and then give me the reference number?
I was able to book you. Your reference number is H9AGMLJM.
Yes, I would like to find a place to eat. Please find me a moderately priced restaurant in the centre.
there are quite a few moderately priced restaurants in the city centre. do you have a preference on cuisine?
Nothing specific, anything in the centre is fine. 
May I recommend the very popular Efes restaurant serving turkish food in the centre of town in the moderate price range.
That sounds like a great place to eat. Can I get their phone number?
The phone number is 01223500005 .  Would you like me to call and make a booking for you?
No, thank you. That will be all. 
Is there anything else I can help you with?
That is all for today. Thank you!
you are very welcome. have a great day.
And you as well, You've been a great help!
