I'm looking for a restaurant, somewhere not too expensive, but not bottom of the barrel either, something in the mid range.
There are 31. What kind of cuisine would you like?
I would like them to serve barbecue food.
I'm sorry but there are none that serve barbecue food. Do you have an alternate cuisine preference? 
how about gastropub food?
All right, sir, the Cow Pizza Kitchen and Bar has gastropub food and it is in the moderate price range. Would you like to make a reservation there?
yes please.book for five, at 1700hrs or 1600hrs and get me the reference number
What day would you like to book for? 
On Thursday please
Sorry, the restaurant isn't available at 17:00. Do you want to try a different time?
How about 16:00?
Yes, I have a reservation available for 16:00. Your reference number is GXV1UIFJ. Is there anything else you need?
That is all I need for today. Thanks for your extraordinary service!
You are very welcome. Please let us know if you need anything else.
