Another pop up sets up shop in the Mandarin Oriental. Now through March from 11:30am to 1:30pm, PHO@MO will take over the Lobby Lounge. Every day, Executive Chef Rachel Klein will make sure there are heaping bowls of oxtail and ginger-scallion chicken broth with noodles, steak, chicken and lots of traditional pho garnishes to keep you full and happy. Drop by the Back Bay hotel on your lunch hour to enjoy a steaming bowl of the deliciousness.
