Gelato! You can always count on close-to-sickeningly-sweet gelato to cool you off on a hot Italian summer day. Rome boils over in the summer and gelato cools you right off, and fills your tummy with delicious sweets. Every stand has different flavors, and variations on the same flavor. I found that strawberry and coffee flavors were consistently delicious, while chocolate was usually hit or miss. Try cioccolato... an interesting mix of chocolate and vanilla.
