Catania's raucous fish market, which takes over the streets behind Piazza del Duomo every workday morning, is pure street theatre. Tables groan under the weight of decapitated swordfish, ruby-pink prawns and trays full of clams, mussels, sea urchins and all manner of mysterious sea life. Fishmongers gut silvery fish and high-heeled housewives step daintily over pools of blood-stained water. It's absolutely riveting. Surrounding the market are a number of good seafood restaurants.
