Start at the bottom of the hill, at the start of Via Roma. Stroll up the hill and window shop. This street is filled with stores, restaurants, piano bars, ceramic stores, and people just like yourself, STROLLING! This street becomes Via Vittoria Colanna at the top of the hill.
When you get to the top, (it's a very gentle slope so don't expect steep climbs!), pick out your favourite flavour at bar Vittoria. (Mine are crocantino, hazelnut liquer, and lemon.) Pick fast as there will probably be a crowd of people around you. (Remember to pay at the cashier first, then select your flavours at the gelati counter outside.) It's about 2500 for a small cup. The plastic cups come in different sorbet colours-I've collected 3 already!
