If you are not a fan of seafood-based dishes you will have to skip this on the list and go on to the next dish. However, if seafood and soup are what you love about mealtime, then tom-yum-goong is going to be your favourite dish in Thailand. This is a clear soup that is infused with delectable and rich flavours of lemongrass chilli, lime leaves and more. This is also one of the most desired and sought-after dishes in the country for both the locals and tourists. This hot and sour soup is something you must definitely try on a cold day or a rainy day in Thailand.
