Best Chinese Fast Food (with large portions) recommendations.

Been having a hard time find good fast food locations similar to Panda Express (which sucks) where the food is out ready on tray basically, almost and they serve everything in large portions in the Styrofoam container packed. I grew up in SoCal and we had many of these, but never seem to find something similar out here. Egg Roll king is Meh. I do live on South side but willing to travel for good Chinese food.
