Ruby Tuesday's in general picked up the pace on their menu and selection a while back. They've also upscaled the interiors a bit as well. The result is great. The variety is a better, you can actually get some healthy fare now (broccoli or cauliflower, for example, over potatoes), and the interior makes you feel like you're out for a nice evening. The service is still the same as most chains- good, not dazzling, and like most chains, there can be a wait at times (even in Donelson). Still, one of the better chains, and a pleasant change from the old days of Ruby Tuesday's.
Besides, there's even a song about the one in Donelson... (see the Superficials on iTunes to hear it)... how cool is that? ;)
