    Food was good and came out fast, we're from out of town and enjoyed the overall experience. Portion was small and I would have gotten more food if I had known. Hot dog and beefsteak was good.

    Best place in town all the food is great and all the decorations give a 1920s - 1940s vibe I was a little bit sad when they started blending their chocolate cake shakes more but you win some you lose some
