Hi, can you help me with something?
Hello, how can I help?
I want to impress my friend from LA, so I'm looking for some fancy expensive pizza
Are you looking for a restaurant that offers a delivery service?
Doesn't really matter tbh
Are you looking for restaurants that offer a reservation service?
that doesn't matter either
In what part of town should the restaurant be located?
I prefer the South part 
Any minimum rating that the restaurant should have?
no, that doesn't really matter to us
I would recommend Legume
That's an expensive pizza place? What a strange name!
Yes, Legume is an expensive restaurant that serves Pizza.
Thanks for your help! bye
Is there anything else that I can do for you?
