If it's fresh crab and lobster you're after, this wharf warehouse is the best place in Cornwall – you can buy unpicked whole hens and cocks or, if you'd rather avoid the hard work, there are prepackaged sachets of dressed white and dark meat, too. Depending on the season, you can also pick up mussels, anchovies, crevettes and more.
It's always worth phoning ahead to check what is in stock.
