If you want teriyaki chicken this is the best place in my opinion. I've been to teriyaki boy and teriyaki madness and I didn't think they were that good at all. The only thing is that it's located inside Galleria Mall so it's not exactly a quick pick up if your not already inside the mall.
I've only really stuck to the chicken but they do have the option for steak and shrimp also. They give you decent portions but if your thinking about taking some home or sharing there is also an option for double meat for a minimal extra charge. Make sure to ask for extra sauce too.
