Wimpy's Braille Burgers

I've written about Braille tattoos, but never Braille food.  Here, Wimpy's burger chain is making Braille hamburger buns using sesame seed to promote their Braille menus.
From the video's description:

"Wimpy wanted to let visually impaired people know that they offered braille menus in all of their restaurants. To spread the word we built braille burgers that blind people could actually read. With the help of skilled chefs we took sesame seeds and meticulously placed them on burger buns so that the seeds formed braille."
