Frozen yogurt shop in Duluth is transforming to focus on burgers
One Chilly Billy's location in Duluth is getting a refresh.
The frozen yogurt and breakfast hub will transform into MadHouse Burgers, a smash burger concept that will ditch the breakfast menu but keep the frozen yogurt.
MadHouse will officially open at 1608 Woodland Ave. on April 26, celebrating its grand opening with free burgers for the first 150 diners.
"This is an exciting new chapter," says Andrew Weisz, co-owner of Chilly Billy's. "MadHouse brings the energy, the attitude, and most importantly, incredible food."
The revamped menu includes the Pulled Pork Smash Burger, Jalapeño Popper Smash Burger, and Bacon Smash Burger, with basic smash burgers starting at $7.99.
The restaurant will also serve beer and retain its self-serve frozen yogurt station.
Weisz and co-owner Adam Daoust took over Chilly Billy's in 2023, purchasing the company from founder Bill Marker, who was retiring but hoping to keep the Duluth shop alive.
While MadHouse opens this month, Chilly Billy's breakfast will stick around on the menu through May 14. Weisz tells Bring Me The News that the company will continue to operate standalone Chilly Billy's locations at the Miller Hall Mall in Duluth and at 2421 Tower Ave. in Superior.
MadHouse Burgers will be open from 11:30 a.m. to 9:30 p.m. daily.
