What is a good recipe for fried fish?

What is your recipe for tasty, crunch and delicious fried fish? I would like a batter recipe that comes out tasty, crunchy and flakey while the fish is flaky on the inside. Any spices in particular that you use? What fish have you tried? What do you serve on the side with the fried fish?
Update: Thank you RJS! That's really detailed. I gotta try that one!
