Now that you’ve seen a hipster pig roast from the inside out, maybe you want to join underground supper club Hapa Kitchen this Friday from 6 p.m. to 9 p.m. for a luau at the BKLYN Yard, the Brooklyn-bucolic patch of grass on the banks of the Gowanus that previously hosted that food-truck fête. Hapa will be roasting a whole hog and working ingredients from Garden of Eve Farm and Tamarack Hollow Farm into dishes like Hawaiian macaroni salad. Ten bucks gets you a plate of dinner and a free beer. Your D.J.'s for the evening, care of Finger on the Pulse productions: Never Forget and Terry Diabolik.
