RESTAURANT (still operating) IN ITALY WITH PAGES/TUNNELS WHERE THEY HID JEWS during WW2.?

Saw this either on National Geographic or Discovery or Travel Channel. Tunnels/pages are behind a closed door in restaurant. I thought it was Rome, but may be anywhere in Italy. Same presenter that did a show on Pompei. Little above average size presenter (man) with dark wavy hair Looks to be late 30's early 40's years old..
