James Beard Award-winning chef Sarah Grueneberg, alongside her long-time Monteverde partners Jaime Canete and Rob Mosher, has officially unveiled plans for their highly anticipated follow-up project: Trattoria Lo So. Slated to open in Chicago’s vibrant Bucktown neighborhood in winter 2027, the restaurant is set to be a significant addition to the city’s dining landscape, with 2026 Emerging Chef finalist Bailey Sullivan tapped to lead the kitchen. This announcement marks a pivotal moment for Grueneberg, who has spent years cementing her status as a titan of Italian cuisine in the Midwest, and now shifts her focus toward cultivating the next generation of culinary leadership.

The Strategic Expansion of Italian Dining in Chicago
The announcement of Trattoria Lo So represents more than just a new restaurant opening; it signifies a deliberate evolution in the business model of Chicago’s top-tier hospitality groups. Following the resounding, multi-year success of Monteverde, which redefined the modern pasta-focused dining experience in the West Loop, Grueneberg, Canete, and Mosher have chosen to pivot to a different neighborhood dynamic. By selecting Bucktown, the group is signaling a decentralization of the city’s “foodie” centers, betting on the neighborhood’s established density and growing appetite for upscale-casual authentic Italian dining.
The Mentorship Dynamic
Perhaps the most compelling narrative surrounding Trattoria Lo So is the appointment of Bailey Sullivan as the head of the kitchen. Sullivan, a standout talent who gained significant industry recognition as a 2026 Emerging Chef finalist, represents the type of investment in human capital that differentiates successful restaurateurs from mere business operators. Grueneberg has consistently championed mentorship throughout her career, but positioning an emerging talent at the helm of a flagship-tier project demonstrates a sophisticated succession plan. It allows for the integration of fresh, innovative culinary perspectives—likely pushing boundaries in regional Italian techniques—while retaining the institutional knowledge and operational excellence provided by the Grueneberg-Canete-Mosher triumvirate.
Designing for Longevity
With a 120-seat capacity, Trattoria Lo So is positioned to be a high-volume, yet intimate, venue. In the current economic climate, where operational costs and staffing volatility remain high, the 120-seat sweet spot is often viewed as the “goldilocks” zone for fine-dining restaurants—large enough to generate sustainable revenue, but small enough to maintain the rigorous standards of service and food quality expected of a James Beard-affiliated team. The winter 2027 opening date provides the team with a substantial runway for build-out, menu R&D, and staff training, insulating the project from the rapid-fire opening cycle that has plagued many post-pandemic ventures.
Bucktown as the New Epicenter
Bucktown has long been a residential favorite, but it has occasionally played second fiddle to the West Loop’s restaurant row. The arrival of a project of this pedigree—backed by some of the most respected names in the city—could catalyze further investment in the area. Trattoria Lo So is expected to draw a dual audience: the local Bucktown residents seeking high-quality neighborhood fare and the destination diners who will inevitably flock to any new concept bearing Grueneberg’s name. This balance is critical to the long-term viability of the restaurant.
The Future of the ‘Trattoria’ Concept
In an era where “Italian” in American dining has become synonymous with everything from red-sauce nostalgia to hyper-refined tasting menus, the naming of the restaurant as a “Trattoria” suggests a commitment to approachability. However, given the pedigree involved, one can expect a refined, elevated interpretation of the traditional trattoria. This aligns with broader shifts in the industry where diners are increasingly favoring “approachable excellence”—a desire for familiar comfort foods executed with flawless technique and locally sourced ingredients.
