I'm from the Boston area, and we are Chinese food snobs. This is the best place I've found in the area. The brown sauces are a little different than New England, but the food is always hot and tasty. Good value, too.
As Asian food goes, this place is pretty darned good. In fact, since China Royal up-and-çlosed suddenly a number of years ago, it's the only "Chinese" food purveyor I choose to use in Chester County. Better plan for take-out though: they only have two tables!
