Mario Batali’s three Las Vegas Strip restaurants will shut down July 27, officials said Friday, as the celebrity chef faces sexual misconduct allegations from multiple women. Batali & Bastianich Hospitality Group partner Joe Bastianich sent a letter to nearly 300 workers about the closures of Carnevino Italian Steakhouse, B&B Ristorante and Otto Enoteca e Pizzeria at The Venetian and Palazzo resorts. He promised to visit the restaurants to speak to employees.
