I enjoyed a lunch here next to the Guidecca canal. I split a GF mushroom and prosciutto pizza and classica salad with my husband. I liked that the pizza was saucy and cheesy. Ask for the gluten free menu. They serve gf crackers instead of bread.
My family recently took a trip to Venice, Italy and I can't say enough good things about how relatively easy it is to eat safely there. I would go so far as to say that the Italians seem to understand Celiac and the GF diet WAY better than most people in the U.S. We ate at OKE on our first day in Venice. My son (he's the one in our family with Celiac) ordered a GF white pizza and gobbled it up. I had a nice grilled vegetable salad and the rest of the pizzas ordered all looked delicious. The GF crust was on the crispy and thin side which my son likes. I tried the lasagne on another visit... it was ok. A little gummy, but for the ability to eat out safely, OKE was just great. Great location on the Zattere, too and you can do take out! They are also AiC certified.
