Sunflour is one of Charlotte's jewels. Although they are known for their cupcakes and other delicious pastries, they also have a great selection of sandwiches. I love the tuna melt in rosemary. In the summer the awesomeness is enhanced by farm or garden fresh tomatoes. They try to source from local growers.
I've been frequenting Sunflour since they opened. I am quite impressed with the changes they have made...padded seating, WiFi, enhanced display of products, and spotlighting local artists.
