My friend eats gluten-free and has many other intolerances, but the staff took very good care of her and she left full and happy. She ordered pasta contadina with gluten-free penne and it was a really good choice.
I had a amatriciana and it really fulfilled my pasta cravings for the day.
This is already a second time i went to Santa Lucia and I can deffo recommend this place
Just so you know there is no gluten-free pizza option - i guess, this is due to regular flour being everywhere on the pizza station and they can't gurantee gluten-freeness.
Ciao.
