I have an afternoon free and a friend who's willing, so I was hoping to find a place where I could sit for a few hours in the mid-afternoon with a drink. Someplace not too sleek; this is less about the cocktail and more about wiling away some free time before reality hits again. Any suggestions - Boston, Cambridge, Somerville? I like Highland Kitchen, but it's not open until later; someone suggested Dante or Publick House but same problem. Thanks.
