We wrote previously about the Nutelleria, an all-nutella eatery that has outposts in Frankfurt and Bologna. Now have come to find out that there is also a Nutelleria opening in Park Slope, Brooklyn. However, it is shrouded in mystery. Is it related to the other Nutellerias? Is it sanctioned by Ferrero (the makers of Nutella)? There is a similar mysterious buzz circling around Montreal’s soon-to-open Eatella. All we know if that neither of these places are planning to open a branch in Chicago (though Chicago’s Eataly does have a sanctioned Nutella bar) – and we need more Nutella options here, stat!
