when I lived in Georgia, I used to love going to this little Japanese place that served yakiniku. it was awesome. when I moved to texas, I went to more Japanese joints than I can remember. only one even knew what I was talking about, although they didn't serve it. so, it's been years since I had any and yours looks great. I have found a reasonable approximation at Ghengis Grill(Mongolian grill place where you pick what you want and thy cook it up) using their sliced beef and steamed rice with equal parts sambal oelek and honey soy sauces. it's not the same, but it's the closest I've managed to find in almost 15yrs.
