I am going to be on the north side of town and would like a recommendation to a high end restaurant for dinner.
I have several high end options available. Did you have a preference on the type of cuisine?
No, I don't have a preference.
Then may I recommend Restaurant Two Two. It is French and tre manufique! Would you like to make reservations?
Have you eaten there?
Yes. Would you like to book a table?
Sure, can you please book a table for four in the evening
I would be happy to make you a reservation, first I will need to know what day and time you'd like to reserve for. 
For 4 people at 13:45 on Saturday. I'd also like the booking reference number, please.
Ok. I have booked your reservation. The reference number is RBBHGYRV.
Great, thanks a lot!
Is there anything else I can assist you with today?
No, that's all. Thank you.
You're welcome. Enjoy your meal!
