One thing America is famous for is the hamburger. So much so that “burgers” were featured as part of New York’s 1939 World’s Fair. Two of the original diner buildings, now sitting in New Jersey, are still serving their famous sliders. Whether it’s with one “n” or two, the burgers and the ambience can’t be beat. Contrary to what the automat Horn & Hardardt would advertise (“You can’t eat atmosphere”), at White Mana/Manna, that’s the whole point.
