I have a lot of choices for you. Any preference on cuisine? There are 4 that match your criteria. I just love the Ugly Duckling, would you like to reserve a table there, or keep looking? I have successfully booked your reservation at the Ugly Duckling for a party of 7 on Friday at 14:00. Your reference number is YNCEB914 . Will this be all? great, i have 23 wonderful options for you! Unfortunately, I don't have anything that fits those requirements. Can I look for something else for you? Unfortunately not. Would you like to try a different star rating? Sorry, still not able to find anything that suits your needs.
I'd like to find high-end restaurant in the center of Cambridge. Chinese would be great. I would prefer it be in the centre. Can I get a reservation for 7 at 14:00 this coming Friday? Please get me a reference number too, I've had trouble in the past with lost reservations. I also need a place to stay. A guesthouse with WiFi would be great. Great, please be sure it's in the expensive price range with a star rating of 2. are there hotels that meet that criteria? How about a rating of two? can you search the type of a hotel?

There are three that meet your criteria. Two are moderately priced and one is expensive. Do you have a preference?
