Yep, the local restaurant we patronize uses large oval plates for serving and the breakfast items like pancakes, eggs, etc., tend to be piled up several deep. I guess this is why when I did calorie calculations for (animal) nutrition class we simply did things by weight.

I have seen the 'artistic' huge plate with the rim used for Picasso-esque sauce-swirls. At least that's low-calorie... :D

A bowl is yet another wrinkle. Or mound.
