During one of my trips to San Francisco, my mom and I managed to do a couple of coffee shops hopping sessions when we were there. Even thought we both don't drink coffee, I think we both enjoy visiting new places and be in a different environment once in a while. Plus we both have an appreciation of nicely designed spaces, such as this one. The Mill is probably one of the more popular cafe spot in San Francisco and I can see why after visiting the place. Plenty of natural light, open space, and nicely designed interiors make it a good place to just chill out or to get some work down. Try out their famous toasts and Fourbarrel coffee if you ever decided to come check out the place.
