I'd like to find an expensive restaurant in the centre.
There are 33 restaurants in the area. What type of food are looking to eat? 
I would like Japanese food. 
I have found Wagamama that is an expensive Japanese restaurant located in the Centre. Would you like to make a reservation?
Yes, can I make a reservation for 4 people at 17:30 on sunday?
Unfortunately I wasn't able to get that reservation. Would you like to try somewhere else?
Yes, I need to find another place like that one though.
I am sorry there are no others in that area, would a different area be okay?
Maybe try one more time, any type of food, exepensive, in the centre of town. 
Okay, I've booked you at Little Seoul, a korean place that is expensive in the centre, with reference number PTWG73V3. May I help with anything else?
No thank you. Goodbye
Okay. Enjoy your dining experience.
