Been here twice, had the kaum poong kee and orange chicken. The orange chicken was great, but the kaum poong kee was really amazing. I highly recommend it to anyone who hasn't tried it.
Also, there are 3 combo meals - sweet & sour chicken + teriyaki chicken, or orange chicken + yakisoba, or kaum poong kee + house chicken - plus rice and drink for only about $8. You won't find many other places where you can get large portions of tasty food for such good prices.
