Have not been to these establishments, but grades are based on overall impact on neighborhood.
YogoMonster. Fresh frozen yogurt with lowercase logo with the funny things over the "o". Straight outta Park Slope. Great addition to the neighborhood. Loses half a grade due to the structure it's located in.
NY Diamond Boutique. One diamond dealer gets replaced by another. Neighborhood neutral.
MB Pharmacy (111-15 Queens Blvd). Grand opening sign, though always seems closed. Big electric flashy sign in window, whose only saving grace is that it probably annoys the shit out of Beach Bum occupants. Windows uninvitingly covered with huge posters.
