Siamais | 149 followers on LinkedIn. Authentic Thai Restaurant in Brum. Food fuelled with flavour, cooked by skilled chefs, and drinks expertly mixed. | Siamais is a family-owned restaurant that has successfully developed roots in Birmingham's hospitality scene for over 20 years, serving the community and visitors authentic Thai dishes and creative cocktails. Siamais name stems from our owner's ambitious goal to create a "dual night out" concept where our restaurant and bar could be used as separate entities or as an addition to the other. In a sense, like Siamese twins.
