I don't this place is that confusing. The way they fill orders (pay and then give your receipt to the person making your order) actually makes sense and is very authentically Italian (all Italian gelaterie do it this way).
In any case, I didn't actually try the gelato but I did have the Illy coffee and that is enough for a four star rating. It is good and strong and tasty. I will continue to return here simply for the Illy caffe and, if I want something sweet, I would also definitely try the gelato.
