The following is the e-mail response from TCBY when asked which of their menu items are vegan:
Thank you for taking the time to e-mail our Customer Service Department and for your interest in TCBY.
Since often what is considered to be “vegan” is different based on the individual, I have attached a list of the ingredients used in our various products so that you can determine what items you might feel comfortable consuming. I hope you find it helpful.
