Zink's American Kitchen is a classy little joint, I don't eat hamburgers, but I have heard that they have some of the best in Charlotte.  The service here was decent and they have delicious salads.  I thought that it was a bit expensive, but the atmosphere is nothing like any of the other restaurants in this area.  The waiters really know the menu pretty well here and some of my friends asked for recommendations and they all seemed pretty happy with the result.  I saw a lot of families around and all of the patrons seemed to keep the language pretty clean, so I would say it is safe for everyone.  It really has an older feel to it, which I like it is nostalgic of a time that I can't really point my finger on though.  This is an awesome place to begin a Friday night.
