They are swearing to tell the whole gelato truth, and risking their cone-holding hands to do it.
So-so, but better than no gelato (still, you might find better gelato in your local supermarket’s freezer section): Blue Ice. It’s so meh. It’s ubiquitous, though, so it may be that if you go to Rome, at some point a gelato craving will strike you… and there will, in all likelihood, be a Blue Ice nearby.
Delicious. Definitely worth a detour. Fonte della Salute (which is very, very close to being up in the next category, and the kids argue is better than S. Crispino). Checco er Carettiere (another one that comes close to pipping San Crispino, and I think is a little better than Fonte della Salute). Pica. By the children's voting methods, Antica Caffe di Teatro Marcello (I will admit, the tiramisu was pretty good).
Contenders of wonderful scrumptiousness. Worth a substantial detour. Ciampini (although they relied almost entirely on standard flavors, their execution was strong across the board). Gelatarmony (their dreamy gelato was worth the cross-town walk with tired children, who also agreed enthusiastically, if somewhat tiredly, that it was worth the trudge). San Crispino (despite my quibbles with their snotty and overly-serious rejection of cones and whipped cream, it was impossible to dispute that their gelato was excellent).
The gigantic ancient Roman disco hand knows Gelateria del Teatro is #1.
And the winner? Hands down, unanimously, in a group of contentious, bickery testers is: Gelateria del Teatro.
