/* ═══════════════════════════════════════════════════════════════
   Osteria al Portone — Milano Bicocca
   Concept: «Dietro il portone». Il nome è il gesto: due battenti si
   scostano e mostrano la sala arancione che il vecchio sito non
   riusciva a far vedere («il sito web non rende assolutamente
   giustizia», scritto da un cliente).
   Palette dalle FOTO REALI della sala: arancione acceso delle pareti,
   mattone, legno scuro, tovagliolo verde, bianco della tovaglia.
