I've seen some commercials for PF Chang's and Panda Express is Chinese food. Haven't you ever seen the commercial with pandas in a zoo talking about their cravings for sweet and spicy shrimp skillets before? It's been a while since I've seen them.
Most Chinese restaurants are family owned. They don't have the advertising money to spend on TV commercials, which aren't cheap, and likely won't be effective, since the restaurants are more neighborhood specific in their clientele. Print advertising and word of mouth is what matters to that type of restaurant.
@kakaburra Kids these days don't be knowin' 'bout that sweet, delicious Tang. ;)
