I've heard a lot of good things about Dolce before I actually visited and I have to say, I've had better gelato. I've also had better service.
I ordered 2 flavors: Reese's peanut butter and pistachio. The peanut butter was very one dimensional and average. Nothing special. However, the pistachio gelato was good, all I can say is they do not cheap out on the pistachio! It was very strong and rich in flavor. This is why Dolce gets more than one star. Other than that, the service was very bad. The person behind the counter was not very polite and seems impatient when asked for samples. The other desserts on the menu such as the nutella canoli and cakes were also not up to par.
If you've got a craving for any gelato that is not pistachio, I would say go to another resturant in Little Italy.
