Great breakfast spot for a reasonably priced meal. Also, they have a train track hung from the ceiling that keeps kids entertained. The food is good and so is the service. All in all a nice spot.

My boyfriend and I were traveling through this way, so we stopped to look for a place to eat lunch. Ruby's Diner came up on our map and had great reviews, so we decided to try it. We walked in and were delighted by the surroundings of the fifties. It wasn't too busy, but busy enough to know that the place was good. We were seated and greeted by our waiter, who was friendly enough. We ordered two different burgers, & I absolutely loved mine. What looked like the manager or owner was also helping wait tables. My boyfriend loves the trains going around, and the very reasonable prices. Overall, it was a great experience! If we are ever in King of Prussia again, we will definitely stop by.

They do some things super well like the burgers and shakes. The chili is awesome. On the other hand, the fish tacos may be one of the most repulsive things I've ever had the misfortune to eat. Stick to burgers and you're good. Oh, and my toddler loves the choo choo. :)

Decent hamburger/shake joint. Sometimes the service seems a little slow. Kids love the nostalgic items and the train that circles the place near the ceiling.

Omg this diner was fantastic! Not only are you paying for the reasonably priced meals but for the scenery as well! I ordered a cheeseburger w/fries and a strawberry milkshake and everything tasted excellent! I unforchanatly live very far from here so i might not be able to come back but it was the best diner i've ever been to!

Everything is delicious! Only let down is they stop serving breakfast, no diner should stop serving breakfast.

It is what it says, a burger and milkshake place. I have always enjoyed both, as well as their chili-cheese fries. Family members enjoy their fish tacos, but not their salads. Service is generally prompt and friendly. Restaurant seems generally clean. I have been going for many years.
