I am looking for a restaurant.
What type of food are you looking for?
I'm looking for unusual food. And I want a place in the centre of town.
I don't have anything matching unusual but I do have an African restaurant in the center of town as well as some gastropubs. Would either interest you?
I'll take something that is cheap.
There are a total of 15 restaurants that are cheap in the centre. Is there another type you would like to try?
Do you recommend a restaurant that is a little more different then the rest?
I would recommend golden house
Is that Italian? I would like an Italian restaurant, please.
Okay, how about the pizza hut city centre? I heard it's pretty good.
Okay, that sounds good. I need to make a reservation for 2 people on Tuesday.
What time would you like to visit? 
How about 13:15?
I was able to book the table for you. It will be reserved for 15 minutes. The reference number is 97AAF776.
That's great, thank you.
Awesome. Have a good day!
