There’s no restaurant genre more hopelessly over-romanticized than the diner. And rightly so! Diners are awesome, both because of their core promise-a cheap, decent meal in a friendly (or, often, a “gruff-but-lovable”) setting-and for their power as nostalgia triggers. Do you have a favorite diner or three from the different eras of your youth, the sites of late-night adventures, hungover breakfasts and goofy aimless hangs with your best friends? Of course you do.
