Why doesn't ANY kind of teriyaki (much less the common teriyaki chicken donburi [bowl] that is so popular in the US) seem to exist in Japan outside the realm of Western burger restaurants (McDonald's, Mos Burger, Freshness Burger, and apparently Subway and Burger King, though I haven't seen them in Japan yet)? It's easily the second most popular/best known and loved Japanese food in the USA, second only to sushi. (I would venture to guess that number three is tempura.) I love those teriyaki bowls, and the truth is that teriyaki IS a real Japanese flavor, so where's the teriyaki? Where are those delicious dons?
