I'm a fan of China Lite. It's take out focused (though has eat in option) and is healthy/semi-healthy Chinese fast food.
Our office is about 100 yards away so we go there often. Pretty much our quick & cheap go to lunch spot. Good food, reasonable, quick and they have a number of healthy options.
Feels at least partly authentic though they do also have several "American Chinese" selections (which I can also enjoy). I'm a big fan of the Szechuan green bean with chicken but sometimes need a good Sargent Chang's chicken or a honey crispy chicken.
My pops is from Canton, China so Chinese food is something we've grown up with. While it is take out/fast food focused, definitely a viable option.
