I actually wanted to go to the gelato place across the road (Heladeria Encantadas y Dulces), but for some reason it wasn't going to be open for another 30mins (and this was 4.30pm). There didn't seem to be much point waiting and the quality at Ravello looked adequate.
Forest fruits (frutas del bosque) and hazelnut (avellana) were alright and filled the need. Just as we finished, the other one opened.
