I need to find out about guesthouses in the north part of the city.
I can help with that.  What price range were you looking for?
As long as it is 4 star, I'm not really worried about the price.
There are about 8 different ones. Most of them offer both free parking and wifi. I can recommend one if you like. 
I would like free wifi. Could you find me rooms at one, four nights for 2 people, beginning Saturday?
Reference number is : DPFNET0I. is there anything else I could help with ?
Yes, I'm also looking for a North African restaurant.
I don't have a North African restaurant right now, is there another cuisine that appeals to you?
no i cant change the type of food
Is there anything else I can help you with at this time?
are there any expensive restaurants? in the same area as the hotel?
What kind of cuisine do you want?
I'm fine with anything as long as it's expensive and near the hotel area. 
There are 5 results for expensive restaurants in the north, would you like to make a reservation? The choices are Chinese, European, French or Asian oriental.
Let's do chinese food, please.
How about The Hotpot chinese restaurant?  It meets all of your criteria.
Sounds great. Could I please book a table for the same group of people at 19:45?
Booking was successful. The table will be reserved for 15 minutes.
