An authentic pickled-herring sampler is a highlight at the pan-Scandinavian Smörgås Chef, which operates three NYC branches. The entrée sampler includes four varieties—with onions, in tomato sauce, in mustard sauce and plain—along with a small mound of ho-hum potato salad. If the $16 price tag has you saying “Uff da!,” go for the $9 appetizer rendition.
