I am looking for a restaurant in the centre of town that serves kosher food.
I'm sorry, but there are no restaurants in the center of town that offer kosher food. Would you like me to check another area?
Are there any kosher restaurants in the city at all?
I'm sorry. There are none.
Alright. Can you find me an indian food restaurant instead? 
Sure, there are 22 Indian places in the city. Do you have a price range you're looking for?
Something expensive please. 
How about the Curry Garden in the city center?
Sounds perfect.  Can you book a table for 3 at 19:15 on Thursday?
I'm sorry I was unable to do so. Would you like to try another restaurant?
Yes. Just make sure it is something in the expensive range.
I was able to book you into the Curry Garden, an expensive Indian restaurant in the city center and your reference number is DHF9VBTS.
Okay great. That is all I need. Thank you.
You're welcome. Good-bye.
