I have not seen their lunch menu, but I think of the restaurant as being upscale dining. Since Shades left that spot, I think many people also have this impression, based on increased number of people waiting in line at Pickles.
I have been waiting to hear good comments about Great Southern before I was willing to go. I have yet to eat there, but now that Franny has tested it out recently for lunch and gives them good marks, I will put it on my list to try.
