Hi, joining a cooking class is a great experience, you should try it. I once participated with my family, my daughter loved it. "banh xeoo" is the dish we learned about. The crust is crispy, the filling is soft. Oh, we also got to go to the vegetable farm to prepare and eat it with banh xeo. Very delicious and a memorable experience for us https://antoursvietnam.com/tours/private-farm-tour-cooking-class-half-day-hcmc/
