The Tick Tock Diner in Clifton, New Jersey, has been a beloved 24/7 institution since it first opened its doors in 1948. It rose to prominence in the 1970s thanks to its iconic disco fries—a crave-worthy late-night staple deeply intertwined with the era’s vibrant club scene. These indulgent fries are piled high, golden and crispy, smothered in gooey mozzarella, and drenched in rich, velvety brown turkey gravy. Originally a midnight favorite, disco fries soon earned their place on daytime and even breakfast menus throughout the ’80s and ’90s. The original version remains a gloriously over-the-top comfort food classic—messy in all the best ways.
