Are there any expensive Portuguese restaurants in Cambridge?
I'm sorry, no there aren't any of those.
Oh no, not even in the west part of town?
Cambridge does have two Portuguese restaurants, but they're both cheap and they're not in the west.
I really need something in the west. Could you try Indian food instead?
I have 5 expensive restaurants in the west side of town. If I may, might I suggest the Rice Boat. They are located at 37 Newnham Road, Newnham. 
The Rice Boat would be lovely. I'll need a table on Friday at 19:00. It should be for 4 people. I'll also need a reference number, please?
Yes I got that for you and your reference number is UJWYM7ZY.
I am also looking for a hotel in the same area with zero stars.
I'm sorry, there are no matches. 
Are you sure?  A 0 star HOTEL in the west side of time. Please check again.
No hotels or guesthouse in the west, can I try an alternate search?
Could you try looking for a guesthouse in the 4 star range?
Ok i have the finches bed and breakfast for you. 
Okay, great. I'll need to book for Friday, 2 nights, and 4 people, please?
Done! Your reference number is 1FPC2TWB. Can I help you with anything else?
No, that's all I need for today.  Thanks!
You're very welcome! Bye!
