Whole Foods is not considered a competitor with Ralphs in the same way that Neiman Marcus isn't considered a competitor with Target. But I thought there was supposed to be a Whole Foods at the Grand Avenue Project?
That block is good for "destination" retail, like Apple Store, Niketown, or the Toys R Us in Times Square, which are all more than just a place to sell goods.
ETA: How about something like
GameWorks? That would be a perfect location.
