While it's not a chocolate restaurant, Disney Springs is planning a themed restaurant kinda like Toothsome:
"Opening later this year, The Edison, a lavish “Industrial Gothic” restaurant, bar and nighttime destination will debut. A collaboration of Patina Restaurant Group and Kinetescape’s Andrew Meieran, The Edison is noted for classic American food, craft cocktails and live entertainment including cabaret. (The Disney Springs location is inspired by its sister location in Los Angeles.) With Old World sophistication and romance, The Edison will be themed to a 1920s-era electric company, recalling an exuberant era of invention and imagination with entertainment that includes contortionists, aerialists, DJs and more."
Bold emphasis is mine.. when I read this, I thought that this was Disney's "response" to 'Toothsome'.
