In the last 20 plus years, I've probably tried everything on Jack's menu. Having said that..I got my favorites.
-Breakfast Supreme Croissant
-Grilled Chicken Strips
-Stuffed Jalapeno's.
The rest of the items on their menu is priced just about right, especially for fast food. Most items on this menu is fried, high fat, and basically not good for you. My stops are usually on the way out or on the way home. Not my first choice for food, but sometimes you just want something quick.
As for their restuarant, it's clean and the service is pretty good. Drive thru is fairly quick, which is the main reason you find me stopping here.
