I've been to Sweet Flour twice now, and have been impressed both times. I love the idea of choosing your own dough and mix-ins to create a custom, fresh-baked cookie, and they always come out of the oven delicious!
The first time I had one of their specialty teas, which was delicious, and the second time I had a latte, which was just okay. The only other negative I can think of is that their sitting area is on the smaller side and the chairs aren't very comfortable, but I think if they were then people would never leave!
