U: I'd like to find high-end restaurant in the center of Cambridge.

S: I have a lot of choices for you. Any preference on cuisine?

U: Chinese would be great.  I would prefer it be in the centre.

S: There are 4 that match your criteria. I just love the Ugly Duckling, would you like to reserve a table there, or keep looking?

U: 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.

S: 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?

U: I also need a place to stay. A guesthouse with WiFi would be great.

S: great, i have 23 wonderful options for you!

U: Great, please be sure it's in the expensive price range with a star rating of 2.

S: Unfortunately, I don't have anything that fits those requirements. Can I look for something else for you?

U: are there hotels that meet that criteria?

S: Unfortunately not. Would you like to try a different star rating?

U: How about a rating of two?

S: Sorry, still not able to find anything that suits your needs.

U: can you search the type of a hotel?

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

U: I prefer the expensive hotel. Can you book it for me for the same group of people?

S: The Express by Holiday Inn Cambridge will fit your needs. How many nights?

U: Do you get a decent value for what you pay here?
S: The Express by Holiday Inn has a few reviews where the customers talk about how overpriced the hotel is.
