One North Kitchen and Bar, 1 N. Wacker Drive; 312-750-9700, restaurants-america.com At lunch, this lively, noisy restaurant, all dark woods and subdued lighting, is packed with suits and biz casual. For good reason. The eclectic menu should please just about any appetite, whether you crave Kobe sliders ($12 for appetizer), salad (Nicoise, Caesar, etc.) in half or full order, steaks or risotto. We tried one of their lunch-only sandwiches, the slow-roasted chicken sandwich (crusty baguette crammed with marinated artichoke hearts, cucumber, goat cheese, basil, tomato and chunks of chicken, $10, above). Yum. It comes with cant-stop-eating-em pommes frites plus slaw. An alternative? The subdued, white-tablecloth ambience (and similar menu) at Emils Bar and Grille (101 N. Wacker Drive; 312-332-4333).
