Hi Ben, here again, another lesson, the explaination for "vegan egg", our auntie, our cook, went to a workshop about being vegan in Vietnam when we told her that our customers asked for vegan banh mi. In the workshop, she learnt about " vegan egg" is when it come from a female chicken never had sex with a male chicken in her life. She believe in what she learnt. We might have different education and veganism is a new thing in Vietnam. But we make an effort to learn about it and cook it for tourirsts like you when you visit Hanoi. We never intent to lie about our food to fool you. We offered homemade cream puff with our drink as a complimentary. The puff is free. If you don't eat egg, you don't have to take it. Perhaps, a lesson for us when we take order to justify and a lesson for you when you order in a local place in Vietnam : toi khong an trung = i do not eat egg. Good luck with your non-egg travelling!
