If Bulgari---then on Condotti.
(although, by the way, it would have been cheaper in duty-free, even after the return of the taxfree, but you understand somehow not ale..)
An iconic place, after the purchase, escorted to the bins: the Bulgari Museum. Meeting, transaction support, everything is at the highest level.
In one of the races, when buying, they made a mistake with the size of the ring, so they exchanged it without any problems, although this practice is extremely rare.
It is recommended to visit.
