How about booking a date night at a high-end Vietnamese restaurant in your area? You could also consider getting him a gift card to this restaurant or for a Vietnamese cooking class experience, where you can take a class together and learn how to make his favorite Vietnamese dishes. Alternatively, you could gift him a Vietnamese cooking kit that includes all the ingredients and instructions to make his favorite Vietnamese dishes at home.
Or you can get him a star map with an important date you share.
