If you’re looking for fried chicken and mac and cheese in Prospect Lefferts Gardens, you should be at Katie O’s. It’s counter-service, and there are only a few tables inside - but it’s great for takeout, and if we made a ranking of potato salads in the city, theirs would be near the top. Just be aware that they make their fried chicken to order, and it takes around 20 minutes. So call ahead of time, or hang out in the little dining room and watch sports on the big flatscreen TV while you wait.
