The people-watching at these Cambridge standbys is almost as good as the hot and cold drinks, tasty baked goods, and menu of light fare (sandwiches, salads, and soups). Many patrons are transfixed by their computers, but enough are unplugged to make the 1369 a fun place for a pit stop. The Central Square location has a pleasant outdoor seating area; the equally enjoyable but less convenient original is at 1369 Cambridge St. (at Springfield St.), Inman Square (tel] 617/576-1369).
