Forget Giolitti's (only really famous because of the number of flavours) - the Gelateria del Teatro on Via di Simone near the Piazza Navona is The best. Many flavours and made on the premises by the family who own and run it, and made with fresh local produce. Reasonable prices too (unlike San Crispino's). The only gelateria to which I gave repeat custom.

I had my best ice cream ever in Gelateria San Crispino. After discovering it, I had to stop there each single day. Sometimes, a great ice cream replaced my whole meal.
Close to the Pantheon I tried once Giolitti, was also great. But I'm in love with San Crispino! Ice cream is cheap too in Rome compared to Paris and London - with a couple of euros you get a big cone with three flavours with whipped cream. I was amazed by the number of available flavours! I found this blog post which is useful for deciphering them.
Ice cream shop near the Forum with Rome’s, if not Italy's, largest selection of soy ice cream - 14 flavours, the chocolate-nut comes specially recommended.
Via dei Serpenti 28
This is Rome's oldest 'gelateria' (ice cream shop). They make the most delicious ice cream, so creamy and so many different flavours to choose from. Buy an ice cream and go to Piazza della Rotonda (where the Pantheon is) and enjoy it while watching the world go by. Not to be missed, not even in winter!
