Stavanger's small fish market isn't a patch on the Bergen version. Still, you can pick up fresh fish here, and try locally harvested oysters, mussels, clams, lobsters and crabs, and the market restaurant does good fish dishes including a majestic, if eye-wateringly-priced, shellfish platter (1550kr for two people). Even if you're not eating, it's fun to look around.
