I lived in Japan for about 2 years so anytime I feel reminiscent of those drunken 4am nights I come here. Not really so much like the ones in Japan though. And I didn't think Yoshinoya was one of the better gyu-don places in Japan anyways.
They should add Japanese curry to their menu. I also wish they offered white meat chicken too. I also agree with the weirdness of the veggie color. I don't know why its gotta be so damn yellow. Just go to Ichiza instead.
