This "foodie culture" has always been a thing. Or at least, has been around for a very long time, more than a century. I would look at a lot of data before saying anything like what you said, I doubt that "foodie culture" has really been an increase in people interested in fancy dining. I think it's more likely just a change in what fancy dining looks like.

But I also haven't looked at any data very closely, so what do I know.
