Glad I found time to visit the very homey Happy End Diner in Greenpoint in 2012, and took in its wonderful semi-circular counter and stools, and menu of tripe soup, borscht, pierogis, stuffed cabbage, kielbasa, blintzes, pig's knuckles and Hungarian potato pancake (stuffed with beef goulash). Because its gone now.
Eater reports that it reopens at the Brew Inn, a fancy beer bar, tonight. Silver Lining: it's still in the family. Martin Cyran, son of the founders of the Happy End, is the owner of the Brew Inn.
