We've ordered from Chen's several times and the food has always been piping hot and tastes good after we get it home.
My only complaint is that the prices seem too high for what you receive in return. For example, we usually order the Happy Family entree and there are way too many mushrooms and not enough chicken, shrimp and beef.
We are big fans of shrimp egg foo yung and the way they make it here is different than most of the Chinese restaurants I've been too.
Their food is definitely good, just be prepared too fork over as much as $65 if you buy 4 dishes and a few egg rolls!
