You're not going to believe me but it's true... the best Chinese food in or around sumter is the Chicken Shack. It's a little place that you'll easily pass right by.
It's in Dalzell, SC off of Rt 521. Cross 521 from Frierson Rd to the T intersection, make a right and follow it until you see a green and pink (yes green and pink) building on your left.
There are only about 5 tables in the place, and 6 things to choose from on the menu but the food there is unbeatable.
For 6 bucks you will get more food than you can eat in a sitting, but you will surely want to try your damndest, and a can of soda. It's no frills, high quality food.
The food is served in the square styrofoam containers and is packed to tight with food and rice that when you open it, the rice is still form fitted in the shape of the top of the container. You get plasticware and soda in a can. The tables and chairs are of an assorted variety from a yard sale or odd lot but you won't notice while shoveling the food into your mouth.
I guarantee that I've just unleashed Sumter's best kept dining secret. I urge everyone to try it.
(And this is coming from someone who thumbs his nose at less than ritzy facilities. there's just no arguing with good cooking).
