Tuesdays and Saturdays. But you have to go there early or wait in line to park. There is a great oriental vegetable section there where you can buy all sorts of exotic vegetables much cheaper than in the stores. If you want some great Bermuda shorts check out my friend, Big Steve, and you can get them for only $5. Brand new. NOT seconds. I'll check out Lox Haven across the street next time I'm there.
BTW, one of Larry's food specialties is STALE jalapeno bagel with melted American cheese in it. When he served me that as a snack while I was giving him eBay instructions, I tossed that against the wall as well. The Bagel hit the wall on the melted American cheese side and slowly oozed its way down. So I gave Larry a sort of kinetic piece of art on his wall. Of course, he did NOT appreciate my contribution to his decor.
Where is this Flea Market? It sounds like it might be worth a road trip.
