In August in BK we went to Masala Art in Thonglor for an authentic Indian experience.
Dinner was excellent, it was indeed authentic, quantities were great, and service was very good.
We didn't have wine but we did have 2 beers.
Total for a couple came to 1800 THB all in.
If you want a very nice Indian experience in BK and would like to be in the heart of the Thonglor area- this is an excellent choice and we were very happy to have come here and will go back again in the future.
