The rap on this restaurant, from what I'd heard, was terribly slow service. That was not my experience. We stopped there on the way to New Orleans. The service was prompt and friendly. The food we ordered arrived quickly. If you want pizza, just order one slice. They are huge. Good, too, in the Chicago style. I usually don't get dessert, but I made an exception for their lemon cake and was glad I did.
One big surprise was the tab. VERY reasonable.
If you find yourself in the Jackson area, around a mealtime, Sal & Mookies is well worth the visit.
