When I was in Chicago in September to run the marathon, I found a paleo- and gluten-free-friendly restaurant called Beatrix. It was just a few blocks from our hotel, and we actually went there twice: once for dinner and once for breakfast.
One of their menu items that caught my attention was a turkey meatloaf with sweet potatoes and kale. I ordered it for dinner on our first night in Chicago, and it was just as good as I hoped it would be.
