I think that some restaurants "matter" in ways that others don't.
First off, we'll go out to eat somewhat regularly at "family" restaurants, that, if not for the frequency of deep-fried items, I can pretty much do at home.
Do these matter? Not really, they're mostly there so I can avoid cooking. I'd even put most (except the top end) steakhouses, and probably even fast food in this category.
A second class is probably best called "ethnic" -- stuff I don't know how to make (yet), or takes a larder stocked much differently than I have, or with equipment I don't have. This includes places like Sun Wah, Smoque, Spoon... in fact the majority of the GNRS.
These places matter. A lot.
The third class is probably the "Michelin Star" category: The brigade system, where it takes time and a large number of people to create my meal. I can't do this, and they can present stuff to me that I can't do at home, and can't afford to do except on special occasions. Do they matter? Sometimes, but I'm betting the ones that matter have to work very hard to stay that way: What has Moto done new lately? Lasers? So 2007. I'm not saying it's old hat, but it runs the risk of becoming quaint. [Note: I haven't actually eaten at Moto, they may have spiffy new techniques and presentations, but I haven't seen the reports here of them]
What is patriotism, but the love of good things we ate in our childhood?
