Could you help me find an expensive restaurant in the centre?
There are 33 in that area. Please choose a food type. African, Asian, British, Chinese, European, French, Gastropub, Indian, Japanese, Korean, Mediterranean, North American, Modern European, Seafood, Thai, or Turkish. 
I want to try Seafood. Can you book for 4 people at 17:45 on Thursday?
I'm sorry, it doesn't look like Loch Fyne has tables at that time, and they're the only one that focuses on seafood. Would you like to try somewhere else?
Please try booking any different restaurant in the same area and price range as Loch Fyne.
Ok, I can book at Bedouin if you would like? They serve african food.
Yes,and book it for 4 people on Thursday at 7:45,thank you.
Ok I have booked a table for 4 at Bedouin on Thursday at 7:45.

No thank you that is all I needed.  Goodbye.
You are welcome.  Enjoy your dinner.  Bye.
