Living in Hawai'i it would strike me how popular CCF was for people that came all that way (typically middle class Americans) and have access to tons of great variety in ethnic places they may not at home, along with local joints that would serve familiar food with the option of local flavour. But some of these comments put it in good context, that it is the familiar and safe choice and has a special or semi-fancy vibe to a large subset of those people.
I don't think I've eaten in one since I was a preteen and may have only been once, but come to think of it, at the time I grew up rural 45 minutes to the nearest small city, eating at cheesecake factory did seem like a special occasion.
