Siam Thai Cuisine is located on the lower level of Ayala Terraces. In terms of space, it is small - but it has nice interior design. Clean and simple.
I haven't tried a lot of their menu yet, but you can check their FB site (click on the Siam Thai Cuisine link). Prices are the usual price range as in other restaurants in the mall. But so far, we enjoyed what we have ordered. And service is okay.
That's my sis indulging me. I asked her to pose for posterity..
Glass walls provide a view to the gardens outside. Their location is also convenient to the nearby parking area.
