I just made my daily stop at the Starbucks on Knox Street. (Yes, I know. I’m Starbucks’ whore. Deal with it.) The espresso maker is remodeling and has set up a sidewalk cafe for the next two weeks. They can do everything except Frappucinos. What makes this newsworthy is how wonderful the concept is: a sidewalk espresso stand. Especially on an unseasonably mild and wonderful winter day like today. In Europe, this isn’t notable. But in Dallas — where fresh air is so often replaced by central air conditioning — sipping an espresso al fresco seems so civilized. Everyone should enjoy it. I say go now.
