We came across this restaurant by chance as we were walking the enormous KOP Mall. Ruby's is side by side w/ a Vietnamese Restaurant. I got a classic cheeseburger that was just the perfect size...tasted great. My vanilla milkshake and French fries were good too....More

Great place to take the kids. Burgers are the mainstay on the menu. Kids love watching the train run overhead and the motorcycles. Good prices and great service.
