A chocolate wall

We arrived at 2ish and after a drink and dropping off our bags we started to explore Rome. He headed to the Spanish steps and Trevi fountain. They were both extremely busy. We spotted a queue coming out of this gelato/sweet shop and discovered there was a chocolate wall at the back of it. It looked delicious! When we tried to find the shop later to get a gelato, we got lost in the maze of Rome's streets.
