Just throwing this out there, knowing it might be totally not what you're looking for:
Shimano A530. Clipless on one side, platform on the other, but not too bulky. I've had them on my commuter for two years now, through thousands of miles, and like them a lot. I think they look a little nicer than clipless that don't have any platform to them. That said, you have to get used to the right motion to flip the pedal to the correct side to clip in. It becomes habit soon enough, not unlike getting into toe clips.
