Sur la Table at the Farmers' Market (adjacent to The Grove) on West Third Street in Los Angeles offers periodic classes on cooking fish, which is an excellent way to learn more about this healthy protein. I saw that there's an upcoming class which concentrates on grilling fish. My friend who has been running the cooking classes program for about a year is leaving to return to her career as a pastry chef at the beginning of July (sniff!) But there are a number of excellent instructors remaining, most of whom have graduated from culinary school and worked in restaurants. I would strongly suggest taking the essential knife skills class (offered often) for anyone who wants to improve their performance in the kitchen, as well as the more advanced class in knife skills (rarely offered) if you want to safe money in the meat department.
Most classes run $69-$79 and end with a good dinner (or dessert) to sample. It is especially fun to take a class with a friend or two. Most classes are hands-on, and I guarantee you will learn something new every time. Plus, there will be a nice discount card to use for a week after the class.
