O'Briens is a seasonal al fresco restaurant on the promenade level of the Riverwalk that serves visitors and Chicago locals alike from May through October. We are open daily at 11am, serving a summer grilled menu of sandwiches, burgers, salads and Fish and Chips paired with an iced cold beer or cocktail. With live jazz music every Thursday and pet-friendly outdoor seating, we can’t wait to welcome you for the afternoon or to start the night at the northeast corner of Wacker and Wabash. A core belief at O'Brien's is preserving our Riverwalk. To limit our environmental footprint, we use recycled, biodegradable cups, plates and utensils approved by the city, no straws and cleaning products safe you and the Earth.
