If you're a fan of chinese foods then be sure to visit this restaurant! It is called Din Tai Fung and this is a Taiwanese staple, many locals would recommend this to foreigners because Din Tai Fung is a Taiwanese-owned company. You will get authentic flavors that you won't find anywhere else.
Be aware that the line is very long! One time, we needed to wait for 2 hours just to eat inside. So we recommend you to arrive early and line up to be the first to enter and enjoy their food. It's worth it!
