We were in Nice for 8 days and ate here 3 times-- the food is that good. This is by far the best gluten free I've ever had in a restaurant. The pizza crust and hamburger roll were better than anything I've had in the US. The non-celiacs in the group also ate gluten free and said it was as good as or better than traditional pizza crust and rolls. The staff is courteous, friendly, helpful, and genuinely nice. And they speak English. The restaurant is at the port, so you'll get done beautiful sunsets and amazing views during dinner.
Right on the harbor, this is a great place for a safe meal. I will say that my choice was not that great (focaccia with sparsely populated zucchini and artichokes), but my daughter had a pizza with ham and mushrooms that was fantastic. And, don't get me wrong, the focaccia itself was good...just sparsely populated. We sat outside, but a look inside is worth it. It is a very cute place.
