I think that is called Je Juk ? and is close to the slipway.
Personally, in Bang Saray, I prefer Preecha - mainly because the missus was unlucky with food poisoning from Je Juk.
My favourite is Lung Suwai (next to Pupen) in Na Jomtien. Although I also enjoyed the BBQ in Naklua at Krathing Lai beach.... forget the name of the restaurant but it is about 500m from Bella Villa Cabana hotel.
