I am looking for a restaurant that serves asian oriental food in the centre of town.
Do you have a price range preference? There are two cheap, 1 moderate, and 1 expensive.
I'm interested in a cheap place. What can you tell me about those?
We have dojo noodle bar, and j restaurant which are both cheap restaurants in the centre of town. Would you like to book one of those?
Yes, get me a table for two at Dojo noodle bar on Wednesday at 16:00
There are no tables available at the time requested.  Would you like to try another time or day?
Hmm.. can you try at 15:00 instead? 
Booking was successful. The table will be reserved for 15 minutes. Reference number is : H6OB1O8J. Is there anything else I can help you with?
No, that will be all.  Thanks!
Thank you, goodbye.
