#185, Brooklyn Heights
This art deco baby skyscraper at 185 Montague is one of my favorites. This stretch of Montague Street begins with a row of towering banks and is pleasantly cluttered farther down with mom-and-pop frame shops pressed together cheek-by-jowl with chain shoe stores. If you can manage to weave your way through the inevitably crowded sidewalks and take a moment to look around you, there are some real architectural beauties. I'm a sucker for anything deco, but I particularly love the panels of elegant geometric decoration, teetering halfway between the mechanical and botanical.
