U: Yes please. I would like that very much and I also would like information on the Ugly Duckling restaurant.

U: Is it known for plentiful food on the plate?
S: The Ugly Duckling is known for having pretty generous portions according to about half of the reviews, but the other half say the portions are small, so I can't be certain.
