Going to Bali with wife in a week and been researching on the web including seafood cafes at Jimbaran. Stumbled onto this site which I guess is a Bali infor site from Japan. The research process had been frustrating and thought I'd share it will everyone.
The site list the names of each and every single cafes on a map along Jimbaran bay. The maps are divide into three areas, the one close to the airport, by the Keraton, and Intercontinental which are the three areas where the cafes are. Click on the areas of the map and will open up a detailed map listing each of the cafes in that area. you can also click on each of the cafea and a picture of the cafe will open up.
I don't know the language but it was quite straight forward or you can try to have it translated on google. Hope this helps and a lovely trip to any one of you heading that way.
