I disagree with the sentiments of previous reviews that this place is difficult to find, or that a taxi is necessary to do so. I walked here from Phra Ram 9 MRT station in 10-15 minutes, and did so easily. The map is very exact, so if you have the Happy Cow app you can use your GPS to guide you right here. If not, I've added a photo of the sign posted place where you have to turn off the road and down a driveway.
This restaurant has a very ambient, zen feeling to it, and although I was here alone and had a lovely dinner, it is perhaps better suited to groups and couples.
The staff don't speak any English, although with the menu being fully bilingual, getting by with pointing is easy. And with that exception they're incredibly attentive and friendly. Expect to pay in the region of 150 baht for each main dish.
The food was very good. My vegetable-heavy stir fry just tasted fresh. And although of the many cakes on display, only one was clearly labelled as being vegan, it was an absolute delight.
It was a chocolate cupcake, but the icing was warmed up and melty, making me for once understand why women always go so gaga over chocolate.
My bill for a passionfruit juice, a main with rice, and a dessert came to 360 baht. And it was well worth it for the food and the service that I'd received. Great place, I'll be back.
