Trader Joe’s is opening its first Brooklyn store, apparently next year, on Atlantic Avenue at Court Street. Will TJ’s hurt Sahadi’s in the areas where the two overlap, like dried fruit and nuts? Or will it help by bringing more “foodies” to that stretch of Atlantic? Is Trader Joe’s completely overrated, especially in New York where the novelty hasn’t worn off yet? Chowhounds discuss it all, at length, as usual. What we want to know is, did the company learn anything about making lines move faster from their 14th Street experiment?
