OK, it was all Thai to me! Being whisked away by a friend's fiancée I found myself walking into this rather large restaurant Somboon that featured a crab in its logo. Not entirely sure what to expect, I let my hostess do the ordering. In true Thai fashion, dishes just turned up as they were freshly prepared and cooked. The "star" dish was, surprise surprise, curry crab. It was just crab meat cooked in an Asian curry sauce which was delicious with just the right balance of spices and richness - all went down swimmingly well with jasmine rice. We also had the classic tom yum koong which was rich and tasty. The koong woosen (prawns with vemicelli noodles) was great, so was the grilled cockles. The mean was concluded with sticky rice and Thai mangoes. Yum yum.
NB: There are several branches of Somboon in Bangkok. Unfortunately, Google has found the site being associated with malware and viruses so can't pull any pictures here. Apologies.
