Can you help me find a hotel in the north?
Yes do you have a price range preference?
Yes I have a moderate price range. 
Ashley Hotel is moderately priced and located in the north.  Would you like to book a room?
Does it offer free parking?  If so, I would like to book it for four nights starting Thursday for 3 people please.
Yes it offers free parking. 
Can I have a reference number for the booking?
Ashley Hotel will be expecting your party of 3 for 4 nights starting Thursday. Your reference number is K5JO25UL. Is there anything else I can do for you?
Yes. I would like to find a restaurant in the same area and price range of the hotel that serves Cuban food.
I'm sorry, there are no Cuban restaurants in the city - is there another type of cuisine that you'd like to try?
What about one that has Chinese food?
I've found one result. It is golden wok. Do you want a reservation?
Yes, I'd like to book for Thursday at 17:15 with 3 people. Send me the reference number too. 
The booking was successful, here is your reference number 0Q4KUTUA. Is there anything else I can do for you?
I will also need a taxi. 
Where will you be leaving from?
I need picked up at the hotel.
What time would you like to be picked up? 
I need to get to the restaurant by the reservation time, isn't it obvious?
I did not want to make assumptions for you, but now you are booked. A black bmw will take you. The contact number is 07551001124
Thank you, and I apologize for getting snappy with you. That is all I need for today.
