A gelato in Rome

Gelato, or italian ice cream, at its best is rich, creamy and much softer than what we can buy in the UK. It's also about my favourite thing to eat in the world. I have, so far in the 3 months in Italy eaten it for breakfast (once) lunch (too many times to count) and dinner (shamefully often). 

Note I don't mean with dinner, I mean when I was out of the house at a dinner-ish sort of time, I deliberately ignored all the more normal, readily available and very cheap street food Rome has to offer and as my friends noshed down on pizza 'alla taglia' and arancini, I picked up a double or triple helping of the good stuff. Shameshameshame. 
I even worked out a system of sorts. Dinner = main meal of the day, therefore my cup must contain only the higher calorie, creamy flavours (no sorbet here) and ideally there will be chunks. 
I have a problem. Yes indeed.

My point is a) gelato is freaking incredible and b) I've eaten a fair bit, and got around little more over three months than the casual gelato munching tourist. So here are my top picks, both locations and flavours. 

Except where I've drawn your attention to it, all prices are essentially the same, around 2-3E for the satisfying medium sized cup in the picture.
