I went to this restaurant for dinner in March 2014 and my overall experience was good.
I took the spaghetti with olive oil, garlic and hot pepper. It was simple and really good, I definitely recommend this dish!! My wife took a pizza with vegetables (the "vegetariana" I believe) and it was ok, not bad nor great (a little bit under-cooked).
Portions are quite generous, so unless you are really hungry don't hesitate to go for the small portion.
Overall it is a good place if you want to have simple Italian food at an affordable price (not that easy to find in Saas-Fee...).
