I'm sure you are not alone. But appetites range from bird like to voracious. So for many people, the entrees may well be sharable. One thing that DH and I agree on is that American restaurants like the ones in the parks seem to have very large serving sizes. Its not unusual for us to share an appetizer and dessert when we have our own entrees. Or to each have an appetizer but share an entree.
But I do agree that there are a few restaurants that serve smaller portions that would probably not be suitable for sharing by 2 adults with a big appetite.
My son would laugh me out of the restaurant if I dare to suggest that we share a meal! The boy can eat!! If we did share, he'd be like your husband, asking for food an hour later. Lol.
We dont do appetizers. We'd rather have dessert. (we cant do apps, entree, plus dessert, that would be too much having all 3).
