I am looking for a restaurant serving Persian food in the expensive price range.
I'm sorry, there aren't any expensive Persian restaurants. Would you like me to check for a different type of food? 
How about any restaurant in the centre?
There are 33 expensive restaurants in the center of town. Which cuisine type would you prefer? 
I think I'd like to try Indian food, are there any of those in the center of town? 
There are 6 restaurants that fit your request. Curry Garden, The Golden Curry, Saffron Brasserie, Panahar, Curry King, and Curry Queen.
Any of them would be fine.
Alright, shall I make a reservation for the Curry King?
Yes please, for 3 people t 15:30 on Friday. Thank you.
Okay done. The reference number for your table is BVK9XZPJ and it is only reserved for 15 minutes.
That's awesome. Thanks that's all i need!
You're welcome. Bon appetit!
