Hi, I'm headed to nashville for 24 hours next weekend. I have time for one lunch and one dinner. Hoping to find some good, authentic country food joint for lunch and would love to do dinner somewhere that is one of the top restaurants in town. Price isn't an issue, neither is location. I'm just one person, but don't mind sitting at a table by myself (although if there is a great spot with bar dining, that works, too). I liked Arnold's for lunch, but seems they are not open on Saturdays. Also have read good things about City House. Any recs are appreciated!
