With just the right amount of blueberries, perhaps the proprietor could prepare a blend in that same shimmering cerulean. As any squeegee man will tell you, however, this particular liquid is suited for cleaning windshields and not slaking thirst. (Display space may be at a premium, sure, but right next to the menu is an odd spot for wiper fluid.) I warmed up instead with a hot cup of ginger tea (small, $1) and also carried off a paper cone of gofio.
