Nifty Fifty's in Holmes, PA is blast from the past. You think you are stepping back in time to the 50's. It is one of those cool diner-esque burger, fries and milkshake places. The burgers are small, but so tasty. And you rarely have a milkshake like this anywhere- they are so rich and creamy. If you are on a diet, you might want to pass up on Nifty Fifty's!
