Exchange has all the requisite young urban professional bar credentials, including a boisterous crowd of suits and loads of flat screens, but its primary gimmick sets it apart: Drink prices fluctuate in 25 cent increments based on supply and demand, and slide across a ticker that hangs over the bar. (So, if everyone at the bar is sipping Jack and Cokes, expect to pay a prettier penny, while prices for unpopular drinks drop). If that kind of thing stresses you out, take solace in the wall of vintage mirrors that greets you in the long and narrow space, and an intimately lit brick lounge in the back offering some calm.
Picnics with a view, roller-skating nostalgia, and a party for gay headbangers.
