What does YMMV mean, I think the disgusting comment is a bit hard. I have traveled in the US quite a bit, the first time I ate breakfast, I was so full I did not eat again till 9pm, your restaurant portions are large. We cruise once a year out of Miami, sitting in the self service restaurant for the first time was a bit of a shock, we were joined by three very large Ladies who ate incredible amounts all washed down with diet coke, they were may I add charming company.
This binge eating did seem to be the norm.
