I ordered the chicken and beef teriyaki bowl with white meat and spicy teriyaki sauce. The first thing I noticed was that the sauce seemed more like hot sauce than teriyaki - if there was any teriyaki in there, it was covered up pretty well by the spicy sauce. Not a bad thing - this sauce was good, just not what I was expecting.
The chicken and beef were both pretty decent - and the rice was fine. The little green onions on top actually made a difference - gave the bowl a little extra flavor.
I prefer Samurai Sam's for fast teriyaki, but I'd probably rank my meal at Yogis ahead of Tokyo Express and Yoshi's.
