Please do not ever get their cooked food. I repeat.. Ever!! If it's on sale/special, it's even worse. The meat used for the food are sub sub sub par and not for human consumption. I felt sick after having one of their 'special' Taiwanese 3 cup chicken.
Any self respecting shopper shouldn't fall for the bright lights, big signs for the sale price or the large quantity.
Btw, you'll only see non-chinese buying cooked food from here but hey I'm a chinese and sadly ... even I was fooled.
