All I can say is...BEST IDEA EVER!!!!
There is no reaxon for a kid to be at a restaurant like this, other than cluesss idiot parents who think they have to infect the rest of the world with their spawn at all times. People might occasionally want a relaxing evening, and that's not happening with kids crawling all over the place and yelling. I applaud this move, and think it should be applied to a couple of other places (California Grill immediately comes to mind).
As an aside, I would kill to eat at this place, as I love the occasional upscale meal. Sadly, I hang around with people that think chicken nuggets are high class fare, so this will likely never happen...
