The Arby's menu uses color coding to draw the eye to categories as well as make the menu visually appealing. They also include a picture of every sandwich, which is very helpful for people who don't know what they want before arriving. The pricing can be slightly steep depending on what you get, but they put enough meat on the sandwich to make it worthwhile.
The cracker barrel menu is the best menu I've seen at a dine-in restaurant. It holds to the theme without sacrificing its usefulness. The color scheme is very simple, but again, color coding subtly finds its use. You can see that some items are shaded in white, and some are in reddish brown, and still others are outlined in red. All items have full and descriptions that not only make it easier to pick what you want to eat, but pick the combination choice that suits you and your wallet. The pricing is heavy, but that's to be expected from a sit-down restaurant. The food is good too.
Cookout's menu is... Honestly comical. It's really packed. Color coding does help, but without the combo menu (not shown here), you're basically completely lost. This menu is very large, but seems more utilitarian than intuitive. It's more there to tell you what they have than what you should order. The combo menu is relieving to this problem, but is usually offcentered from this much more confusing menu. The pricing is awesome for the quality and quantity of food.
