When we go to MIL's, generally around 2-2:30.
When we go to BIL's out on Long Island, generally not before 4. (Traffic is a b*t*h & it takes forever for people to arrive.)
Both places, dessert is always about 1 hour after dinner is finished. Kindof a long, stretched out day of feasting!
I like eating late much better. When I was growing up, dinner was always a noon sharp!!
