This store at the corner of Pennsylvania and Sutter Avenues was originally a Key Food store about three times the size. 2/3 of the original Key Food store is now a Dollar Tree, and the remaining 1/3 has been converted into a Shop Fair Supermarket. There is another Shop Fair at 256 Livonia Ave at the other end of Brownsville.
The store looks very big, but that's because we're looking at the side here, and it was cut from front to back. The Shop Fair is only about 5600 square feet. It's no longer listed on the Shop Fair website, so I'm not sure whether the store is still in business. It's located at 340 Pennsylvania Ave, Brooklyn, NY.
