I love me some take-out Chinese. My body is programmed to crave it every Sunday night.
I've never eaten at Little Shanghai (only take-out) but what everyone is saying is spot on... very 1990's Chinese restaurant decor, which I kinda love. It's absolutely not a place I'd want to go for a date night (I'd feel very upset I'd wasted the time and effort getting cute because you probably won't see other human beings - probably why they offer a 20% discount for sit-in dining) but its great for good, reasonably priced take-out Chinese food.
I've had four-star experiences at Little Shanghai but in general I'd give it 3-stars. I get Moo Goo Gai Pan - basically chicken and vegetables and its good but could use a little more flavor. My husband gets the sweet & sour chicken or Seseame Chicken and they could use some vegetables and more chicken, less breading.
The house fried rice is tasty and the egg rolls are pretty good. It looks like I need to try this Pu Pu Plater everyone is raving about.
