This is the infamous Plant- a vegan eatery in Itaewon.
I'm pretty sure there are other vegan stores around but this has got to be one of the top listed vegan spot known amongst foreigners here.
The dining space is relatively small and the mains are pretty straight forward and limited per day, which is good for fickle minds to decide. A refreshing spot to try if you are planning on eating a little cleaner before digging into that bbq for dinner.
All the mains are served with a small portion of chips and pasta.
Directions to the store can be found here.
