The burger: The diner-style cheeseburger – you know, the double-stacked, skinny-patty, dipped-in-nostalgia monster that's camped out at the top of the burger popularity charts -- is no longer the exclusive territory of well-run independents such as Saint Dinette, Nighthawks, Lake & Irving and Revival.
The chains are getting in on the action. Including Punch Bowl Social, the Denver-based newcomer that landed in November in the Shops at West End in St. Louis Park.
The chef of record at the fast-growing chain – it's currently operating in eight cities, with nine more locations on the docket – is Hugh Acheson, he of Atlanta's Empire State South and 5&10 in Athens, Ga., and a familiar face thanks to a steady stream of appearances on "Top Chef" and Top Chef Masters."
Acheson's involvement infuses the restaurant's diner-inspired menu with its southern accent. In St. Louis Park, his recipes are executed by chef Erick Dominguez, who let me in on a secret: the quarter-pound patties that make up the restaurant's first-rate "Knockoff" burger don't get the traditional smash on the flat top grill; they're formed before they hit the heat.
"That's the key," he said. "You smash them, and they lose some of their flavor."
He's clearly doing something right, because the kitchen is selling 1,200 to 1,500 "Knockoff" burgers each week.
It's an all-chuck formula, generously seasoned and taken to a uniform medium. No pink, but still fairly juicy.
From there, the Big Mac model is followed fairly closely, which probably explains that "Knockoff" name. The cheese is American, with two gooey slices; one, placed between the two patties, adheres them together in an irresistible beefy-cheesy marriage. Toppings include crisp chopped iceberg lettuce, tangy pickled onions and a side serving of sweet, crunchy pickles; all enhance rather than mask the beef-and-cheese party.
