I got email from the owner of RestaurantWatch.com asking me to link to his website. I took a look, and it definitely got some good content.
I was surprised to discover that 98% of restaurants get a rating of A or B from the Health Department. Either Los Angeles retaurants are really very healthy or grade inflation extends beyond high school and college.
It turns out that you can get much of the same information directly from the LA DHS, but RestaurantWatch.com provides a better UI.
