Reading through the mammoth thread on the shortcomings of Park Slope grocery shopping, I was suprised to find so many posts evincing a desire for a Fairway or Gourmet Garage to open in the neighborhood. I live in Cobble Hill, where the shopping is admittedly better, but to me, these guys are not the solution. What they do is put all the little stores--butchers, fish mongers, green grocers and cheese shops--out of business and turn the neighborhood into more of an Upper West Side than it is. Now I know that some Slopies are saying, "but we don't have a butcher to put out of business!" but if Fairway shows up, there never will be a butcher. And the nice green grocers that you do have along Seventh Avenue will suffer.
(Trader Joe's is a different story. I've personally called them and cordially invited them to Brooklyn. To my mind, the only business they'll threaten is the supermarkets, who could stand a little threatening, to my mind.)
