Menus are still pretty elusive! I think I spotted two or three across the entire lounge area. If it helps with finding them, they're in a book now with a black flowery patterned cover...

Menu itself is mostly the same as what corporate-wage-slave posted earlier, although it shows a beef-and-potato curry instead of the lamb curry...

EDIT: Just spotted a bunch of menus underneath some magazines/newspapers on the bookshelf in the dining area. It's on the right side just as you enter the dining area. Maybe that's where they're all hiding!
