The Rabbi of Chabad in Dumbo is giving hashgocho to the very first kosher place in what is a hopping new neighborhood. That is amazing, many kosher people working there. Sort of vegan place, with juices and interesting baked goods on the corner of Jay Street and John down by the water. Looked interesting and eclectic. I tasted some cookies and muffins made from almond flour, a but dry but delicious. Its called FIYA (not sure what that means or why). The owner's name is Dov, and he says he opened last week but does not yet have the full menu.
