This seafood stall is on the Cha Am beach road. It's between Cha Am South Soi 5 and Soi 6. Coming from Bangkok, turn left at the junction (traffic lights) on Petkasem Road towards Cha Am beach. Go till the end of the road and turn right at the T junction. Drive along the beach road passing Soi 5 and you'll see the stall on your right.
You can order your food here and ..... ...enjoy your meal under the umbrellas on the beach, across the road.
You get fresh seafood here and the price is very reasonable.
