Kathryn: Yes. Except for flowers. And I will go whenever.

Spring through fall is the best time to go. The market is really small on Mondays, so I skip it. And I find Saturdays entirely too crowded. So I typically go Wednesdays and Fridays, in the morning. If you get there after 10 or so, you'll find that some vendors have already sold out of items.

Most of my money goes to Honey Hollow, Ronnybrook, Andrew's Local Honey, Windfall Farms, Berried Treasures, Mountain Sweet Berry, Terhune, Yuno's Farm, Eckerton Hill, and Keith's, but I don't often buy poultry/meat/eggs.

If you can get to the market on Saturdays around 8, it's not crowded - and Saturday is by far the best in terms of selection. My favorites include Lynnhaven goat cheese, Terhune peaches and cherries, Yuno's greens and eggs, Northshire Farms eggs, Keith's lettuce, garlic, and herbs, Millport Dairy cheeses, Our Daily Bread (much better than Bread Alone, to my taste), Hawthorne Valley yogurt, Evolutionary Organics greens. And seconded on Buzzard Crest - their grapes are phenomenal!

Thanks guys. I see a couple of things I already buy: Yuno's eggs (suggested previously buy someone here), Hawthorne Valley yogurt- I originally found it at Whole Foods. I also buy Milk Thistle's milk. I saw Keith's booth today and hadn't seen garlic like that before(forgive me, I'm still learning), I will definitely grab some next time.

Gorzynski Ornery Farm has incredibly unusual, interesting, and delicious produce, and uses super environmentally friendly growing techniques. Those 2 women from New Jersey with the cheese stand have unbelievable sheep milk ricotta. And, of course, Milk Thistle is amazing.

@QueenAlli - I'm referring to seasonal produce, so it's silly for the reasons I stated: the same vendors can have inconsistent offerings based on the particularities of their location. One week one vendor may have the nicest x, y or z, the next they may be less appealing than someone else's. That's all. You have to shop around.

bread alone has wonderful whole grain breads. my current favorite is the harvest 9 grain. i also love the eggs at flying pigs farm, the norland potatoes {pink on the inside!} and shallots at paffenroth gardens, and anything that franca at berried treasures grows, particularly her raspberries, tristar strawberries, and sungold tomatoes.

There are, however, some really good vendors that don't come to Union Square on Saturdays like Honey Hollow, Berried Treasures, and some of the seafood folks.

Maxwells Farm on M has great produce at great prices. Kernan Farms from NJ on W has also has great produce, check out the whole basil plants. Fabulous Farms on W, F and S has great plants, including great little cacti and succulents.
