I will be going to WF next Saturday for a 7 on 7 football tournament. My wife will drop me off at the venue around 8:30am, and then she'll have 4-5 hours or so to kill. What can she find to do between shopping, wine shops, etc?

Drive by and see if they'll turn the Falls on for her.

I really don't have a serious answer. I haven't tried the restaurant linked below, but I've seen it on TV and it looks fascinating

Thoughts and prayers for your wife. Just kidding. Born and raised in WF, but left 11 years ago. The best part of WF, used to be old, restaurants and bars in town. Sadly, many aren't there anymore. There is a small museum near MSU's campus, the "country club" neighborhood is another dose of nostalgia, and the last I heard, they were renovating the "falls", so it might not be running. I live in Lubbock, nowadays and rarely go back, as most of my family is gone. Good luck!
