I want crossover food at an expensive price. Can you help?
I'm sorry but we don't have any restaurants meeting that criteria.  Could you please try a different type?
is there something else in the West?
Grafitti has great British food in the west and fits the expensive pricerange you are looking for. Does this appeal to you?
Actually, I'd prefer a European restaurant. 
Cambridge lodge restaurant has good reviews and serves European food.
Please book for 1 person, sunday at 17:45.
I'm afraid they're full on Sunday at 17:45. Perhaps another day, or another time slot?
How about Sunday at 16:45 please for 1 person?
You are booked for Sunday at 16:45. Your reference number is 2W56MF47. May I help you with something else?
That's all. Thanks for the help!
You're welcome! Have a nice day!  Goodbye.
