I am vegetarian, and I am Asian. So, I guess I am bound to look for a couple of nice Asian vegetarian restaurants in Bangkok so I dont get stuck with the same place all the time.
The first to recommend here is a vegetarian Japanese restaurant, in Soi Tong lor, called Chijuya.
Really easy to get there, just catch the monorail from Siam square and get off at Tong lor station, then head to 55th PLaza building, about 10 mins walk from the main road, or a few mins if you fancy the motorbike taxi :-)
You will find the lovely Japanese meal like California roll, sushi, tempura .. bla bla…, complete vegetarian (I think vegan can eat here too).
official address is Chijuya, Fifty-Fifth Plaza Sukhumvit Soi 55, 2nd floor. (I am not going to tell the phone number because I dont want anyone to think that this is one of those ads … )
Another place is a Thai-Chinese vegetarian called Suki Jeh Ru Yi (means Ru Yi vegetarian sukiyaki). It locates itself in a tiny soi opposite the Bangkok Center hotel on Rama 4 road. The soi is next to railway station, called Soi Phraya Singhaseni
Here you will find a really tiny diner hidden in the unseen corner, and loads of lovely foods that you will completely forget it’s vegie food..
If you fancy Thai traditional food done in vegie style, this is the right place. They also do good noodle dish too..
The official address is Ru Yi vegetarian sukiyaki, 285 Soi Phraya Singhaseni Street (at opposite Bangkok centre hotel, north of Rama 4 road, near Hua Lampong railway & MRTA station) .
I’m happy to answer on email of how to get there.
