From Mainichi:
Thousands of hungry people flocked to Yoshinoya restaurants across Japan on Friday for a special one-day revival of its popular beef-on-rice dish, with one excited customer smashing his car into a store and another customer becoming violent because the beef bowls had sold out.
The Yoshinioya [sic] chain suspended sales of beef bowls, or gyudon in Japanese, on Feb. 11 last year, after the Japanese government banned beef imports from the United States following the discovery of mad cow disease there.
Gyudon is delicious. I know how to make it, nyah nyah!
