I am so hungry I made the mistake of eating the katsu-don pork bowl) at Yoshinoya today...a disgusting substitute for the guyo-don (beef bowl). It just isn't the same. It doesn't work. It's gross. I am almost willing to go all the way out to Tsukiji just to have a beef bowl. They are serving beef bowls at the original Yoshinoya in Tsukiji to preserve the beef bowl heritage. They are using Japanese beef and it is not the same...but better than that disgusting pork thing they have manifested in the wake of the US Beef "Scandal" as the Japanese press refers to it. It sucks that the Yoshinoya in Times Square is serving a beef bowl made with American beef, a proper one, yet in Tokyo I cannot get one...I demand satisfaction!
