Plenty of seafood restaurants in Johor especially around JB area. So far, only been to Orang Asli, Senibong and one at Sg Rengit. I would rate Orang Asli the best in term of quality and price. I find Senibong a tat too commercial. They employed alot of waiters and quite expensive.
Many seafood restaurants in Sungei Rengit area (after Desaru) in this GPS mapsource installer including the popular Jade Garden, Sin Kong Seafood Restaurant, Restaurant Good Luck and Restaurant Sg Rengit. There are a few others, not listed in this installer, such as Paradise Seafood, You Kee Seafood, Jade Garden Seafood, Beautiful Village Seafood Restaurant but can be found in another GPS map.
