Ariana Grande and friends popped a bottle of Dom Pérignon to enjoy with fresh burrata at Siena Tavern. Comedian and actor Adam Sandler was spotted in a brightly colored Fila jacket at Hugo’s Frog Bar, where he graciously posed for photos. An ever-suave Mario Lopez snacked on cheese curds and Stasi Twists at SafeHouse—completing the ballerina-style clearance test required for entry at the spy-themed spot—before heading to TAO Chicago for dinner. Unwinding from his busy schedule as a Shark Tank mogul, Mark Cuban spent some time soaking up the glamorous 1970s vibes at DISCO. Cellist Yo-Yo Ma stopped by the newly revamped Le Colonial for lunch, enjoying himself so much that he returned for dinner the same day.
