A play on the term for Venice's flooding, acqua alta, this tiny but bountiful shop operated by a social cooperative sells natural, fair-trade products, some from Third World artisans (therefore "altra," or "other"). The quality is notably higher than some similar stores, and there is a wide range of items, including shampoo, jam, hand-knitted scarves, reusable cotton cloth to wrap food, herbal teas, coffee, water bottles, and more. If nothing else, buy a bar of the delectable Modica chocolate, made in Sicily following the Mesoamerican cold-processing techniques introduced by the Spanish.
