Walnut Street Café is a University City mainstay serving innovative riffs on American comfort food from an award-winning team. Executive Chef Jack Peterson balances elevated techniques and approachability to create seasonal menus that champion high-quality, local ingredients. Walnut Street Café is owned and operated by Warren HQ — the hospitality group behind Sunset Social and The Post also located in the Cira Green building — in partnership with Brandywine Realty Trust. Walnut Street Café is open Tuesday through Saturday, serving lunch, dinner and weekend brunch. In 2020, Walnut Street Café introduced a new sister outpost, Walnut Street Market, to better serve the community amid the global pandemic by offering an open-air market selling fresh florals, locally made pantry staples and a fresh, grab-and-go menu.
