I don't know much about gelato to be honest, but I always get pistachio when I do get some. Their pistachio is good, but I've had ones that are more on point with the flavour. Also, this place doesn't seem to have as much varieties compared to the gelato that's just a few blocks over.
I did try what everyone else talked about already, which is the Rocky Rocher. If you love Ferrero Rocher, you have to get this. It seriously does taste like the real thing. If my review is only based on this one thing, I'd give it 6 out of 5. Yes, it's that good.
