i go to the House of Yang quite often, but I can't say its great. It is close. Serving size is pretty good, but its a case of quantity over quality. Everything is gloopy or greasy, and usually smothered in a brown sause. It seems like all the parts are there, but there was much care in the cooking or assembly. I often get back to my desk, open the bag, and the bottom is covered with brown sauce.
I'd say their fried rice is very good, but the rest, just fair.
