Union Square and Flatiron Guide: Things To Do and Where To Eat with Kids

The adjacent Flatiron District and Union Square neighborhoods are two of Manhattan's most unlikely kid-friendly areas. Even though both are filled with office buildings and chain stores, there are lots of amenities for families if you know where to look. Both Union Square and the Flatiron District boast beautiful parks with destination playgrounds, a great selection of family-friendly restaurants, and one-of-a-kind attractions like the interactive Museum of Mathematics, the foodie wonderland that is the Union Square Greenmarket, kid-lit haven Books of Wonder, the sculpture-filled Lego Store, and a very magical Harry Potter New York.

Because the neighborhoods encompass less than a mile together, families can easily explore both Union Square and the Flatiron District in one day, even with a short-attention-span toddler in tow. Of course with so many things to do, see, and experience in this 15-block stretch from 11th to 26th Streets between Fifth and Park Avenues, you'll probably need more than just a day to hit all the recommended stops in this guide to Union Square and the Flatiron District.
