It’s not an easy time to be opening a new restaurant anywhere, let alone one in an area that’s not typically thought of for its cuisine. But Arlo, which debuts today in Mission Valley at the revamped Town and Country resort, is hoping to attract local diners to Hotel Circle. At least, that’s the goal for chef Josh Mouzakes (Joël Robuchon at the MGM Grand Las Vegas, The French Laundry, and Hotel del Coronado), who wants to bring more culinary prestige to the neighborhood.
