Last month I e-mailed Vienna in Chicago. Today I received this e-mail from their customer service department. I hope it helps someone.
Thank you for your interest in our Vienna Hot Dogs, unfortunately, we do not have any retail outlets. You might try www.loutogo.com. There are some Deli's that handle our Hot Dogs, such as Nate n Al in Beverly Hills 310 274-0101, Labels Table on Pico, 310 276-0388. Hope this is helpful to you. Ronni
