Somboon Seafood Siam Square One is a seafood restaurant on the fourth floor of Siam Square, in front of BTS Siam Station. Its signature dishes are pu pad pong karee, a spicy and sweet fish dish, and stir-fried morning glory. Arriving at opening time can still mean a wait: tell staff the number in your party, take a queue ticket, and check the number on the display board. The food is decent, but prices run on the high side.
