I would give this flea market 3 stars for the merchandise, 5 for the people watching. It's a whole…read morelot of fun, but I didn't find much I really felt like I had to have. Most of the merchandise is over-priced and kind of junky, but there are some fun things to be found if you want to pick through.
Really the reason to go here is for the experience. Pinheiros is a very cool part of Sao Paulo that always seems to have something interesting going on. The atmosphere on Saturdays, when this feira is held, is electric. Street musicians, people walking their dogs, and hipsters abound. There is also some great restaurants to check out if you get hungry while browsing through old records, 50s furniture, and all kinds of memorabilia. Funky boutiques line the sidewalk across from the fair, so if you don't find anything to your liking at the feira, you may end up taking home some graphic tees or cute vintage dresses from one of the nearby stores.
