If you are celiac in San Vito you are safe: many restaurants are in the AIC circuit (Italian Celiac Association).
However, if you are also vegan, you can only hope that the evolution is faster, because we are in the Stone Age.
Then you get a pizza, so you can choose the ingredients. But at that point no one informs you that the pizza base is not made by them! So you get a flat, defrosted, hard as stone thing and when you point it out they also tell you that it is the best in the country..
The photos speak for themselves.
Never before have I left a pizza on the plate in my life.
However the prices are good (and necessarily) and the waiters are very fast.
