I've got Albatross bars on my city bike-- they're lovely and afford me a very upright position that makes looking around (especially behind me) much, much easier than with drops. They do make the bike somewhat noodly in terms of handling, but I can ride this bike all day and be comfortable. They're not my first choice for riding fast, but the tradeoff is how secure I feel in city traffic riding with them.

Wow, that Ant looks a lot like my bike, right down to the saddle and bell.
