I've been a fan of the Bluewater Grill for a couple of years. Despite the fact that they are a (small) chain, the seafood and fish are consistently fresh. Try their cioppino, it's got verve and the serving is generous. I have yet to enjoy a great bouillabaisse in LA but looks like I need to get over to La Cachette!
