Review for Aria Resort & Casino Review For Union Restaurant & Lounge Google User Jul 4 '15 at 3:34 Had a very special family gathering in Las Vegas and decided to try Lavo as "the place" to dine together. What a treat! The wait staff, led by Matt Zompa, was friendly, efficient, caring and served our needs, even though we never knew they were there. The food was outstanding, especially their famed meatball. Ambiance was upscale but not overbearing. Wonderful experience. View full site to comment or like
