When Doug closes a door, Frank and Patty open a window. Frank Meats Patty (3324 N. California Ave., no phone yet) will replace the loudly and lengthily lamented Hot Doug’s in the location that was formerly recognizable by its line stretching down Roscoe Street.

The partners behind Frank Meats Patty also own Lockdown and Fatso’s Last Stand, and much of Fatso’s menu will appear at the new counter-service spot. “We’ve got a secret menu at Fatso’s Last Stand that will go on the menu at Frank’s,” says Bob Corbett, the general manager, citing the shrimp po’ boy with coleslaw and cheddar, and the Ooey Gooey hamburger, which has a cheese-filled patty like a Juicy Lucy.

The owners also hope Frank Meats Patty’s menu will carry some homages to Hot Doug’s. They may offer duck-fat fries on weekends, as Doug’s did, and possibly a game burger of the month to nod to Doug’s game sausages. “We don’t know sausage the way Doug did, but we do know burgers,” Corbett says.

After getting in November 1, the Frank Meats Patty’s crew hopes to redecorate and open by December 1. With that quick a change-over, there may even still be a few Doug’s devotees lined up.
