Question: what is huong xa xi?
Answer: Fanta Sarsi (Huong Xa Xi) - 330ml. ... This Vietnamese Fanta is flavoured like Sarsi or Sarsaparilla, which is a Vietnamese soda very similar to root beer! Sarsi is traditionally flavoured with the Smilax ornata plant, but is also now sometimes flavoured artificially. Try this unusual Fanta flavour whilst stocks last!
