Catania's raucous fish market, which takes over the streets behind Piazza del Duomo every workday morning, is street theatre at its most thrilling. 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.
