It turns out that guy who called himself a chef was actually not one; he was a part-time server at the restaurant in question.
Now, whether or not he was writing down the wrong order or not, we don’t actually know at the moment.
If I was the chef at Florindo’s, the real one, that is, I would take this opportunity to really reach out to the gluten-free community. Everybody know his name now, might as well use it for good. 🙂
