Who:   The liveliest cross-section of Gothamites you'll find in any one place, period.
What:   A city park with a historic past, Union Square is an urban gathering place where anyone from flatiron execs to film school students can sprawl out and relax.
Why:   The farmers market, which brings the freshest baked goods, cider, and goats milk cheese all from upstate farms, is what makes the city livable.
