I have to say that some of the best food I have ever tried is whilst being in Calis. I have had amazing meals at La Casa Di Mamas, Harem and Barbella's.
I suffer from coeliac disease and was so worried about eating in a different country especailly since in England I have been made ill from cross contamination. But the staff I met at the restaurants were so helpful and made me tasty gluten free food.
Barbellas even made me a gluten free brownie on my secind visit there.
I couldn't pick one great restaurant in Calis because I rate so many of them. But I will say that the Sicilian chicken at La Casa Di Mamas is delicious!
