Din Tai Fung is famous because they supposedly used water with healing properties to make their baos. This is of course BS, but it's a selling point. Each bao is individualled wrapped a specific number of times so they all have the same number of folds.
How to eat the xiao long baos... I never knew this even after eating at their branch in the United States.
If you're too lazy to read the instructions above I tried to make a video on how to eat them.
In my opinion the food is good, pretty darn good, but not that good to warrent the high prices. The prices in Taipei compared to the branch in Arcadia were about the same.
I don't think you have to go all the way to Taipei for Din Tai Fung. There's a branch in Arcadia (near Los Angeles) and they pretty much taste the same.
