Demolition is underway at 131 and 131A 6th Avenue in Park Slope, formerly the sites of Sadie Mae’s Cafe and G-Laundry, respectively. According to public records, the owners of the 6th Avenue Deli next door paid $1,671,700 for the two small storefronts in February of last year. (Clearly we are in the wrong business.) Their DOB application for a new two-family, three-story building was approved in June a full demolition permit followed in July. And it looks like bad news for locals who like food or doing their laundry: The storefront space is going to become “community facility medical offices.” GMAP P*Shark DOB
