Time Out says
Watch more than 2 dozen flavors of tiramisu being hand-made, or pick up colorful macaroons or a host of gourmet items at this inventive café and grocery.
Tiramisu, the classic Italian dessert of mascarpone cream over espresso-soaked ladyfinger cookies, wasn’t invented in Venice, but I Tre Mercanti make some of the most creative varieties you’ll find anywhere—like mango, salted caramel (yes, please) or matcha green tea. At this elegant café and gourmet shop, you’ll also find gorgeous macaroons, plus cheeses, olive oils, and balsamic vinegars, all great gifts to take back home as souvenirs of your trip to Venice.
Time Out tip: There’s really no place nearby here to plop down and enjoy a picnic, but I Tre Mercanti is a great place for stocking up on provisions if you’re heading to Lido, Giudecca or the Biennale Gardens for the day.
