According to Grub Street, Stevie Wonder suggested Duane Martin provide a menu written in Braille for Xen’s visually-impaired customers. Duane did just that. That is something that most restaurants don’t do. Well, at least, I don’t see any Braille menus nor have I seen anyone blind order food at a restaurant. So now we know that there is a possibility we might meet Stevie Wonder if we visit Xen Lounge.
