This place was quite difficult to find. I came close using google maps but ended up taking a taxi for the last 100 yards. My advice would be to just take a motorcycle taxi from the Ratchadapisek MRT station. Call the restaurant and give the phone to the driver so that they can direct him.
On to the food. As another reviewer said it's largely just mock meats, so if you don't like mock meats I'd stay clear. Having said that the quality of the food was excellent though pricey by Bangkok standards.
I was the only one at the restaurant when I arrived (it was close to their afternoon closing time) and at the end of the meal they kindly offered to take me back to the MRT station on motorcycle. I tried to tip the guy but he politely refused.
Overall I had a good experience here. Not a whole lot to add to the other reviews but just want to keep the reviews fresh and up-to-date!Pros: mock meat heaven, great service
Cons: expensive , hard to find
