The last survivor of a once 10-strong Union County empire, this tiny metal diner on Raritan Road has been smashing golf ball-sized beef clumps into oniony sliders since opening day in 1947. Still run by the Collins family after three generations, the Clark outpost turns out breakfast all day and those paper-thin-pickle-topped burgers on poppy seed rolls — griddled classics that one writer called American Zen. Crinkle-cut fries are hot enough to burn your fingers and cheap enough that regulars have been coming back for decades.
