Review of TCBY

I'd eaten here before - JUST the soft serve with no added toppings. I ate here last Sunday and got only GF-labeled ice creams. Plus the caramel & chocolate syrups (each in its own container) after verifying with the worker that they were GF (according to their allergen notebook). I don't know whether an ice cream machine was cross-contaminated or if it was the syrup, but I hurt worse than I had since being hospitalized 2 years ago (when I was diagnosed with gluten sensitivity).
