Portillo’s Brings Breakfast to Five Chicago-Area Locations | Eater Chicago

"This Niles suburban site is part of a five-location pilot testing a limited-time breakfast menu from a national Chicago-born fast-food chain. Operating 6:30–10:30 a.m. during the trial, the menu includes a Polish sausage with egg and cheese sandwich on French bread (and a vegetarian version), a bacon-egg-and-cheese croissantwich, doughnuts provided by Stan’s Donuts, fruit cups and hash brown bites, and coffee and other beverages from Metropolis Coffee. The rollout is designed to leverage existing supply-chain items—particularly eggs used in seasonal sandwiches—to streamline implementation." - Serena Maria Daniels
