Bobbie's Dairy Dip (just like the good ol days when I was a kid in a small town. I love Bobbie's)
Las Paletas (unique and standard flavors but they are all excellent and fun)
Elliston Place Soda Shop (Another one that seems to have been around forever and yet forever young)
Places I have heard about but haven't been to yet...
Do you all know of any other places in and around Nashville that are good?
