Disappointing. Service was good, the atmosphere nice, plates were served very quickly, prices are fair, the food was absolutely fine, but ... lacking the Thai finesse and it was not spicy at all. We had curries with two chillies on the menu, and even for german taste it was only a bid hot. If you order it specifically spicy they add chillies that are not spicy. And to put that into perspective, in other Thai restaurants I order the curries little spicy / hot and I am sweating - and I would never eat the chillies put on top because they are too hot.
So, if you are happy with European stile Thai food go there, if you expect expect spicy / authentic Thai food ... well.
