Fans of Portillo's rejoice: a new restaurant may be opening in the South Loop.
The chain applied for a building permit at 520 W. Taylor St. last week, according to city records. The restaurant would be the second location in the city.
In April, the Oak Brook-based chain also applied for a permit in Gurnee, which is set to open in November.
A request for comment from NBC Chicago to Portillo’s wasn’t immediately returned.
