Looking for suggestions for 50th birthday

My (49F) birthday is Friday, the big 5-0 and I have no idea what to do. I really don't want to deal with Nashville so I am hoping to find something fun to do in the area. I am looking for a grown up place to have dinner with a group of friends, not looking to do the whole getting drunk at bar thing, been there done that. I have looked and apparently the only event on Friday is the tree lighting. If you have a Dec birthday you will understand how much I would like to have my birthday separate from Christmas. So I have decided to see if any local Redditors have some suggestions because I just don't know what to do.
