This soup is more of a starter esque dish and is common all across the restaurants in Sukhumvit and the rest of Bangkok. A classic dish whose origins stretch way back, Tom Yum Goong has multiple variations in the county. The Thailand version of the soup is known for its spiciness and if you are someone who does not prefer extremely spicy dishes, you might want to ask the cook to tone down on the spice. The major ingredients in the dish are mushrooms and freshly caught prawns. For spice and aroma, curry leaves, lemon grass and chillies are made use of.
