1 place I recommend
This is the one place in Cremona I have eaten at myself and would recommend.
An osteria on Piazza Alessandro Gallina, a few streets from the Duomo. I had a really good meal here but in terms of ambiance I think it really matters which room they put you in so make sure to ask (unlike me).
Address: Piazza Alessandro Gallina 1, 26100 Cremona, Italy
