We visited this restaurant whilst staying nearby. When we visited Sant'Antonio semed to have a festival in town (Saturday night) and it was very busy. Fortunately the welcoming staff were able to find a table for us. The menu is not available in English but luckily one of the waiters was on hand to help us out.
I had a mushroom tagliatelle dish and my husband had the local speciality curlogiones (ravioli with a potato filling). The food was absolutely delicious. The restaurant had a great atmosphere, there were several large family groups celebrating and despite our minimal Italian we didn't feel out of place at all.
Coffee and dessert followed, and the bill was very reasonable for what we had. Definitely worth a visit if you are in the area.
