Another vote for the Shimano dual sided pedals like the A530. I've got them on both my road and my touring bike and love them. I ride with walkable MTB shoes and sometimes will clip out in stop and go traffic and ride the flat side, then flip-n-clip when I get open road. Some people complain about having to flip the pedal, but with a little practice it becomes intuitive. If you miss the flip, big deal, pedal on the flat a few strokes then flip again. It's also nice to be able to jump on the bike and ride comfortably in street shoes for recreational rides with the family, or quick errands.
