The first thing to know about Aba is context: a high-rise, view-conscious room in Chicago, United States, matched with the ambitions of a Mediterranean restaurant. The draw is brightness, produce and a relaxed sense of generosity; at a polished mid-to-high price point, it should be judged as a polished dinner worth planning ahead for. Read it as a place for a meal with a clear identity, not just a convenient table, with the final judgment depending on execution, hospitality and consistency across the meal.
