Our daughter got a glutenfree pizza, they could also offer glutenfree pasta. Seemed to have full control over this!
I was in a big group and was just planning to get gluten free pasta but they were so kind and offered me gluten free appetizer (prosciutto with some cut up cooked pizza dough with oil and salt) and also dessert. The gf food is nothing out of this world but the staff make a strong attempt to make you feel included in the whole experience. And they bring out all of the gf stuff first and know all about cross contact etc. amazing for big groups!
