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: Do the portions fill you up?
S: The Ugly Duckling has really big portions that will fill you up, apparently. I only found two reviews that said otherwise.
