I want to go to a restaurant in the centre that serves gastropub food
There are three gastropubs in Centre, are you particular about the price range or would you like a recommendation?
I need it in the moderate price range please. 
I think you'd enjoy The Cow Pizza Kitchen and Bar located at the Corn Exchange Street.  Would you like me to book a table?
Yes, could you book The Cow Pizza Kitchen for 8 people on Friday at 17:30? 
I have a reservation for 8 people on friday at 17:30, your reference number is ZKOGBRMR. 
Can you help me find a guesthouse that has 0 stars and free wifi, hopefully in the same area as the restaurant?
The El Shaddai is in the centre part of town, has free wifi and 0 stars. Would you like me to book it for you?
That sounds perfect, I'll need it for 2 nights on the same day please.
Sure, how many people should I book for? 
I need the reservation to accommodate 8 people please
Booking was successful, and they will hold your table for 15 minutes. Your reference number is ZKOGBRMR. Is there anything else I can help you with today?
That is all for now. Thank you for all your help.
You're welcome and enjoy your stay.
