Bar Culture in NYC, London, D.C.--and Baltimore?

Megan McArdle has an interesting blogpost (and resulting "discussion" in the comments) at the website for The Atlantic; in it she attempts to make the case that onerous government regulation negatively affects the nightlife/bar scene in Washington D.C., and, yes, is why you can't fight your way into ChurchKey on most evenings.

There are comments from a Baltimore resident about the comparable-yet-different bar scene in Baltimore in the article's comments.
