Some things are better in principle than in practice. Examples include electronic paper, conscious hip hop and the 2009 version of the Kansas City Royals. I lump Broadway Cafe into that category. I admire their endurance. The Westport coffee shop managed to outlast a neighboring Starbucks. I also love spotting the array of bohemian types constantly lounging outside. For all that, however, the place just doesn't work for me.
