My family and I have really enjoy Chinese food and W&K is one of the best in the fort mill / carowinds area. Is everything perfect? No, but the chicken or shrimp with broccoli (a standard in any Chinese restaurant) has a phenomenal sauce and I cannot recommend their shrimp dishes enough - their shrimp are massive and there are always a ton in every order).
My parents enjoy shrimp Kung pao (no water chestnuts or baby corn - they do add or remove ingredients as you desire!) and the shrimp with broccoli with cashews. I prefer the shrimp and chicken with broccoli because each has a delicious sauce and when combined are fantastic (and add cashews). The sushi is also very fresh and delicious, made by the sushi chef to order. It is also inexpensive at dinner (half off) and worth grabbing if you like sushi!
I have never gotten a delivery and cannot review that service, but we are regulars and know the staff by name and vice versa, we are always treated very well.
