The Dolce Restaurant is a diner in Chicago featured in the 1934 arc. Sham, acting as Ricardo Russo, a member of Jacuzzi's gang, and a Lamia informant, lures Graham Specter, Jacuzzi Splot, Christopher Shouldered, Sickle, and "The Poet" to Dolce for a confrontation in order to get everybody to team up to take on Nebula.
Dolce is owned by a certain elderly couple -- the same elderly couple who decided not to board the Flying Pussyfoot (they wanted to go to the springs) on December 30, 1931 after the wife had a bad feeling (premonition) about the train. While they were debating what to do on the platform, a man named Elmer C. Albatross approached them (having overheard their discussion) and bought their tickets off them since he wanted to board the train. Thus, the couple had their money refunded, and Elmer got his own wish in turn.
