I don’t see it reflecting a sense of extreme luxury on the community as a whole because a yochid businessman decided to open a grocery store, keep it well kept and have some sections in the supermarket sell fancy prepared food items. All it reflects is that he thinks (perhaps/hopefully correctly) that there are enough people able to purchase those products for him to make a profit after paying his workers for preparing and maintaining those sections.
The verbal tour would fall generally along the same lines you gave for Pomegranate. (The valet parking there is because in Brooklyn you have a lack of parking problem.)
