The Tastee Treat is a great old fashioned drive-in in Yankton, SD. Tastee Treat features a "loose meat sandwich". When my fiancee and I first started dating, he couldn't wait to take me to the Tasty Treat. The loose meat sandwich is good. It is not a bbq sandwich, it is loose seasoned beef without a sauce. It is still very flavorful though (without a sauce) and can be made even better with ketchup (or mustard). The drive in also features fantastic shakes, fries, burgers, and icecream. They have a drive up feature where you can eat in your car, just like the good ole days. You can also eat inside or at a few picnic tables outside.
