Not having been here that long, I hope this isn't old territory.
Let's say someone is a picky eater. They only like rib eye steak, baked potatoes, and chocolate souffle. However, they are willing to drive all over town looking for the best and spend a lot of $$$ on those foods.
Is that person a CH?
I think not. I think a CH/foodie/eGulleteer/gourmet, etc. is someone with an adventurous palate. Obviously some of us have certain things that we don't like to eat (kidneys, cilantro, what have you). However, IMO, to be a gourmet, you gotta be willing to eat a wide variety of things.
