Union Square in New York City is a well known landmark. It occupies a large block between 14-17th Streets and Park Ave and Broadway.
I love shopping at its famous Farmers Market (Greenmarket) held on Mondays, Wednesdays, Fridays and Saturdays, 8AM-6PM, year round. It is a colorful and lively market where you can find fresh vegetables and fruits as well as honey and preserves, eggs, poultry, meat, seafood, tasty baked goods and breads, beautiful cut flowers and plants and even some hand made items. There are also cooking demonstrations and other events such as book signings held regularly at the Square.
