hello
Hello, how can I help?
I need a cheap priced restaurant. I do want the raiting to be higher than 4.
I can filter restaurants by name, location, food type, its average rating, whether or not they take reservations, and whether or not they have a delivery service.
I would like something that has a rating higher than 4 and is cheap please. 
What cuisine are you looking for?
I'll take Italian cuisine. 
In what part of town should the restaurant be located?
Can it be in downtown?
Are you looking for a restaurant that offers a delivery service?
No, that is not necessary. 
I have found a restaurant named The Porch.  It is cheap and has an average rating of 4.  The restaurant serves Italian food and is located in the center of town.  Would you like me to continue searching?
Is there anything that has a rating higher than 4.
Yes.  Tamarind follows all of the same criteria and has an average rating of 5.  It is the only restaurant that fits this criteria and also has an average rating of 5.
Okay, that is perfect. Thank you. 
Would you like to search for any more restaurants?
