Blacky's Sims Zoo has a really pretty dining set up for grabs. You must register first (for free) to get this and the other goodies they have updated with. The registration is not in English, but I found it quite simple with no problem to figure it out.
Make sure to stop by Club Crimsyn and grab yourself some multi-placeable wheat and grass. A couple different sizes and colors to choose from. Also check out the converted scarecrow that came wth Sims 2.
