17th Street Market
Take the kids and make an outing of it; this fish case has the biodiversity of a big-city aquarium. We especially love the delicate baby octopus, beautiful enough to be jewelry, and the Fisher-Price-colored blue and green parrot fish that remind us of happy times snorkeling in tropical seas. The fishmongers behind the counter know their stuff and can suggest simple recipes, or if you're feeling lazy, pick up a pint of the ready-made ceviche and a spoon. Go on Saturdays when there's live music from an array of local and international musicians as diverse as the offerings in the fish counter.
