Beekman Bar and Books
889 1st Ave, at 50th; 212.758.6600
While people incessantly bitch about "rules, man", restraining human behavior can be a positive: "don't touch the third rail" prevents certain death, and "don't touch your sister" prevents certain Elephant Babies. For elegantly strictured imbibing, hit Beekman Bar and Books.
Beekman admits their dress policy carries a slight "f*ck you factor", but if you're denied they'll comp you a free drink at any other Bar and Books location -- initiating your new rule, "must show up nightly in man-tank and K-Swiss".
