Edit: Also check out All Good Things, she sells vegan cookies. And there are a couple vendors with vegan soaps and lotions-- The Laughing Pear has all plant based products except their Milk and Honey soap.
A business I was just informed to have vegan products is Dad's Perogies- has a variety of vegan perogi, cabbage rolls and also soups.
It's an okay market, wish there were more specialty vegan products offered. Lots of fresh produce and bread though.
Also "In the Raw" makes fresh almond milk which is delicious.
And they always have live entertainment.
