I won't drive here from downtown Madison specifically again, but if I'm in the area I may stop. I think it is pretty hard to mess up mac'n'cheese (which they don't), but it is difficult to make transcendent mac'n'cheese (which they don't quite).
The interior as a kind of Chipotle or Noodles & Company vibe inside. Lots of Wisconsin rah-rah stuff on the walls, predictably.
I had Memphis, with pulled pork and little crunchies on top. It was great! Really good idea to mix up the texture with the crunchies. Companion had buffalo chicken or something of that sort, his was not as good as mine - no crunchies and the oil from hot sauce pooled up.
They serve it up in little tiny faux-cast iron pans which have adorable hot pad mitts on the handle. This was the best part, these cute tiny mitts.
Takeaway: strip mall food that's pretty good, stop if you're around.
