These new steak houses have multiple private dining rooms.
1. Mastro's Steakhouse—a chain with locations in California, Arizona, and Las Vegas—opened its first Chicago outpost in October. Occupying the former Blue Water Grill space in River North, the venue houses four private rooms. On the second floor, three rooms can each host seated dinners for 32. The rooms can also be combined to hold dinners for 96. Dubbed "Mastro Four," the largest private room can accommodate receptions for 100.
2. Overlooking the Chicago river, River North's Chicago Cut Steakhouse opened in September. Two private dining rooms, referred to as Sonoma and Napa, can each seat 45. The rooms can also be combined to host dinners for 100. Each room offers an independent sound system and a 46-inch monitor that can hook up to laptops.
