I read on Reddit that Mr. Piña on Havemeyer closed. I walked by and saw like 5 people just staring at the empty storefront wondering what to do. There was also cheap produce there.
There are other Mr. stores around and the closest one in Greenpoint probably isn't farther than Mr. Piña was, but I liked it because it was convenient for my citibike points and my trips to Trader Joe's and Whole Foods.
