That would be one way of looking at it. Though we don’t know exactly what percentage of their sales are orange chicken. Just having something on the menu doesn’t automatically guarantee it’s the big seller.
However, if trying to apply it as some sort of judgement or standard, or to set up a joke, it fails. The SCV and AV are no more awash with orange chicken than most of the San Fernando Valley or most of the rest of L.A. for that matter. One could even say, so fucking what? I’ve seen orange chicken on Thai menus minutes from North Hollywood’s very good Thai restaurants. Orange chicken sums up most Chinese anywhere around L.A. outside of the SGV and a few spots scattered around the Valley, South Bay and Westside. And by a few spots, I mean very few. And, that applies pretty much everywhere around the U.S., save for a few pockets. We are “orange chicken nation.”
Of course, the way some folks look down on the Valley already, that probably means nothing. And, if they look down on the Valley, then they’re really going to look down at the valleys further out. As is in full evidence here.
