I have been in Italy recently and I personally found to enjoy the gluten free foods there. I agree that some can be expensive but got around this easy.
Although there are some Italian brands you will also find the international ORGRAN brand of pasta and their huge selection of gluten free foods which are the best in terms of quality and price. For traveller it is a brand to be familiar with as it is available in USA, Europe, Australia, New Zealand and even found some in Bali.
I'm not boasting about this brand but I am grateful for the quality foods they have made available for us coeliacs.
When I was in Italy I found the ORGRAN products by chance while travelling through Rome and realised the head office was located there.
Their email address is
info@orgran.it They respond very quickly but it helps if you know some Italian as their English can be a bit difficult to read.
Enjoy
