Party House One
Time Out says
The lunch buffet at Party House One at Siam@Siam offers a mix of Thai and Western cuisines. Make a beeline for the dessert section and indulge in their cake offerings. The Opera cake is an absolute winner. Imagine how soft cashmere feels against your skin; this is how the cake feels on the tongue.
