CROCCA is a pizzeria located in Via Vigevano in the Porta Genova neighbourhood. They have Roman style pizza, which is a low and has is crunchy compared to Neapolitan pizza.
This is not my favourite style of pizza, but Crocca is a great spot if it's something that you might like.
It's pretty affordable as well, expect to spend around 20/25€ per person.
They have other branches across the city too, I pinned just the one in Via Vigevano, which was the one I tried.
