It's hard to come by good Chinese food all the way up in Cave Creek, AZ but J Chen will satisfy your cravings. It won't blow your mind, but it's consistent and tasty. I'm a huge fried rice fan and theirs is definitely a great option.
My only recommendation is to take the food to go. I've been to the restaurant on Saturday and Sunday nights and the inside is dead. It's a large restaurant and it would just feel weird being the only ones dining in. So get the food and take it home and enjoy it while relaxing or watching a movie.
