Portillo's opens smaller flagship on Chicago's Michigan Avenue

Portillo’s is betting that a smaller downtown footprint can still deliver the kind of volume it wants, but the move also signals how the chain expects restaurant labor to change. The company’s new flagship at 304 North Michigan Avenue, just south of the Magnificent Mile, will cover about 5,500 square feet, seat nearly 100 guests and handle dine-in, pickup and delivery. It will be Portillo’s first in-line restaurant in Chicago and only the second in the system, a sign that the brand is testing a different operating model in a space where every hour and every station matters.

Portillo’s announced the project on June 5 and framed it as a “pivotal step” in its growth strategy, but the sharper message for restaurant workers is that the company is slowing down. Portillo’s cut its annual new-unit target from 12 to 8 and said it is limiting 2025 and 2026 openings to already signed leases while it focuses on restaurant-level economics and more efficient capital deployment. That is a very different expansion posture from the aggressive buildouts that often bring a wave of hiring, training and internal promotions along with them.

For crews, a 5,500-square-foot prototype can change the job in practical ways. Smaller dining rooms and an in-line urban site usually mean tighter back-of-house space, closer coordination between front- and back-of-house teams, and more pressure to cover multiple channels at once. Pickup and delivery add another layer, because staff have to keep in-person service moving while also managing off-premise tickets, staging orders and handoffs. In a format like this, managers often lean harder on cross-training, which can give some workers more skills and more flexibility, but can also mean leaner staffing and fewer people to absorb rushes when lunch or weekend traffic spikes.

The rollout also shows how Portillo’s is trying to grow beyond Chicagoland without overcommitting to oversized stores. The company said it had 102 locations across 11 states as of fiscal 2025, and later reporting put the total at 104 after two of eight planned fiscal 2026 openings. Those planned openings include the company’s first airport location at Dallas-Fort Worth International Airport and the new in-line Chicago site. For restaurant workers, that mix matters because prototype choice shapes who gets hired, how shifts are built, how much training is required and how much room a unit has to create steady career paths as the brand expands.
