Keifer's is absolutely the best casual place to go for dinner or lunch. It is Greek-based food, and absolutely delicious. Try the pita motz definately and any of their wraps, but be sure their feta dressing comes on it: this dressing is amazing. You can even order the dressing alone to take home with you, and it's worth it. Another good side (if you want more than the pita motz) is their cottage fries. The prices are more than reasonable, and it tastes great. You can eat inside or outside. I don't live in Jackson anymore, but whenever I visit, I make sure I get to eat at Kiefer's at least once: it's that good.
