  `With a screeching sound, a page containing ${theMenu} slowly emerges, line-by-line, from a dot-matrix printer:`,
  `In the shadows cast in the cavernous space, you see the forms of ${theMenu}:`,
  `With a low hum, standing waves appear on the reflecting pool at your feet. Impossibly, they spell out ${theMenu}:`,
  `You see a box of candies labeled 'Eat Me'. Why not? you think. You find ${theMenu} printed on the wrapper:`,
  `You see an ornate bottle labeled 'Drink Me'. Why not? you think. You take a sip and shrink to the size of a doormouse. Now you can read ${theMenu} scratched into the wainscoating:`,
  `Cretaceous jungle plants tower overhead, overgrown from the safari room. The ancient fractals of the branches prefigure the structure of ${theMenu}:`,
