First off, let recognize what cook out for what it is. A fast food place. The food is good but not out of this world in taste. However, this is what I survived on in college (and still sometimes)! The price is a deal and a cookout tray is the way to go! I'm always satisfied.
Just a few things about the trays..I really like their onion rings and hush puppies but they only give you 3 or 4 so if you are really hungry get the fries. They give you quite a bit. I personally always get a corn dog. So good!
Finally, last word of advice. GET A MILKSHAKE! You can make any combination of flavors that you want for one price. Amazing.
