bk - In addition to what DR SWW already said....
I thought you had at least mentioned Crustacean, Lawry's (in one of it's incarnations), and The Ivy in your notes and/or posts at one point or another? Hmm.. Maybe that was another L.A.-based DR or two.
A bunch of those places are downtown, and were set up around the Disney Concert Hall, so they've already been around for a couple of years - and show no signs of stopping or closing right now. And according to the descriptions in the magazine, only a small handful have been open less than two years. Again, the list seems to be very slanted toward "fine dining" experiences, and you don't seem to slant that way.
I think they also do a "Cheap Eats" issue, so you may be more familiar with some of the places listed there. *And I do not treat "Cheap Eats" as something bad or "low". Heck, my favorite issues of Washingtonian, New York and Time Out New York magazines are their "Cheap Eats" issues. Low in price, high in quality and flavor.
