Some morsels of food news today: Zagat Buzz reports that Shanna Pacifico is leaving Peter Hoffman’s Avenue B restaurant, Back Forty, to be chef at his reboot of Savoy in SoHo. Meanwhile, Grub Street hears that The Smile (now getting competition from the newly relaunched Acme as NoHo’s sceneiest spot) is opening a takeout-oriented offshoot on Howard Street near Crosby Street.
