Gelato in Rome

A new movement toward artisinal gelato has revitalized the local scene, and the city of Rome now certifies select shops as Gelaterie Artigianale. These shops use only fresh ingredients, no pre-made bases, and no artificial colors, flavors or emulsifiers. Look for signs displaying the symbol -- a large "A" -- if you're interested in experiencing the difference. If nothing else, try to avoid places whose gelato features bright, artificial coloring.

Gelateria del Teatro - Via di San Simone, 70 (5 minutes walk from Piazza Navona)
Just off the pedestrianized Via dei Coronari, between Piazza Navona and the Lungotevere Marzio. This newish place is a gelateria artigianale, using carefully sourced ingredients including almonds from Bari and pistachios from Sicily. The picturesque location offers outdoor seating in a tiny alley; the gelato itself is heavenly and includes several flavors of chocolate ranging from milk to "puro" -- reputedly 70% chocolate. Other choices include cassata and tiramisu flavors plus caramel-pear and ricotta-fig-almond.

San Crispino - Via della Panetteria 42 (1 minute walk from Trevi Fountain)
A rave review some years ago in the New York Times raised this gelateria's profile and it remains wildly popular with tourists; there are often lines out the door. Inside, the gelatos are stored in stainless steel bins with lids -- they take ice cream very, very seriously here and everything is made from scratch, using only fresh ingredients. Its flavors are creamier and more ice-cream like than some gelatos; the San Crispino and crema di limone (lemon cream) flavors come particularly highly recommended.
* Shop is really small so open your eyes wide and look for it!

Giolitti - Via Uffici del Vicario 40 (4 minute walk from Pantheon)
This is a very old establishment -- it opened in 1900! -- and is often voted best ice cream in local polls. The high-ceilinged interior recalls the turn of the last century, with mirrors and marble and table seating; the staff are friendly and the selection vast. Try the crema marrone (chestnut), which was a favourite of Pope John Paul II, who sent his driver to pick up a tub whenever he was in the mood.

Ciampini - Piazza San Lorenzo in Lucina 29, close to Via del Corso and the Spanish Steps. Ciampini is a favorite with locals, and offers good, reliable ice cream.

Della Palma - 20/23 Via della Maddalena, 2min walk from Pantheon
Baskin Robbins of Rome, with countless flavors and varieties (lots of soy choices, frozen yogurt, etc.)
