The radical makeover of the formerly cramped and blah Associated Supermarket on Fifth Avenue in Park Slope is complete. The expanded store is now open, although it’s not fully stocked and the new deli and other sections await food. The grocery took over space occupied by the Donuts Coffee Shop (whose demise was widely mourned) and Beso (whose disappearance caused fewer tears to be shed by some). The new store represents a major upscaling. Now, if they could only remove outdated products from the made over shelves, things would be humming along smoothly.
