Burger Inn is an old-timey but cheap looking burger joint with appropriately cheap burgers. The burgers were about more or less the level and price of fast food burgers, and reminded me of that Burger Baron in Gasoline Alley were I once had the misfortune of stopping at.... okay maybe not that bad.
If you're really craving a mediocre but cheap burger, as sometimes one does, this is not a bad place for it - but I definitely wouldn't go out of my way to eat here.
