Slightly off topic because I'm not in Japan...
When we had one Japanese customer from the Watami chain visiting, we had several options planned for dinner, but he and his colleague said they liked Yakinikku. Since that was not on our planed menu, we said, well, yakinikku's good, too, but there are more interesting stuff. His short, firm answer: "Yakinikku !" as if he had been thinking of Yakinikku all the time !
I thought, okay, this gentleman really likes beef !
The best yakitori I had was done by a Korean fastfood place in Berkeley. Since I liked it so much and had it for lunch 5 times a week or even 7, I finally got to ask for a recipe, which the owner gave after much hesitation. The funny thing about the recipe was that it was exactly the thing for yakinikku, and not something else. I never got to perfect my skills, but the taste of the bar-b-q chicken was soooo good !
Right next door was a Chinese family from Japan; interesting mix of culture there. I loved their vegetable dishes. So healthy, too. From my viewpoint, it appears that yakinikku isn't as popular as it used to be some 20 yrs ago in Korea. I wonder if it is due to higher beef prices, or the availability of other meats, or simply because of the mad cow scare. Yakinikku not being on our plan is only one sign of this change. I wonder if this is happening elsewhere; although it seems in Japan, it still has some appeal. With some controversial services or watering down maybe ? Was the establishment run by a Korean, Japanese, or mixed ? I'm sorry you got short changed in your yakinikku experience. Restaurants do vary drastically depending on who runs it. The bad ones are usally selected out for bankrupcy naturally; how else would it be ?
