This is that good old American standard, a drive-in restaurant such as was common in the 1950's. You drive your auto into a covered spot, read the menu mounted on a roof support, and place your order using the speaker next to you. Shortly your order is delivered on a tray designed to hang from your partially closed driver's side window. When you are finished with your meal, you signal the carhops and they remove the tray, and you back your auto out of the space.
The menu includes the expected foods for a drive-in: hot dogs, hamburgers, cheeseburgers, hot dog baskets, burger baskets, fish baskets, etc. I happen to like their coney dogs and their root beer.
They are located on the east side of the Parkway just north of the boundary between Pigeon Forge and Sevierville, and just south of the Tanger at Five Oaks Factory Stores.
