Siam Umami - Portland, OR

Siam Umami, Thai Restaurant in South Portland

Royal tradition, local imagination

Royal recipes, local ingredients, and careful presentation shape the experience here. At Siam Umami, Chef Tong brings a point of view beyond Thai American flavors, rooted in Southeast Asian tradition and shaped by a Portland kitchen culture that values creativity. 

 The menu moves past the familiar with Chor Muang, La Tiang, and Duck Red Curry, each plate built with detail rather than excess. The room feels casual, cozy, and intimate, with a natural style that suits slow dinners, creative cocktails, and conversations that get to linger.
