Piazza Don Bosco. Via Principe di Belmonte 117. Serves pastries, drinks and ice creams at the tables on Via Belmonte, a street closed to traffic. Piazza G. Verdi. Opposite the Teatro Massimo.
Opera is convenient, and it has an indoor tea room as well as outdoor tables.
Via Re Federico 115. It's in the Altarello district near Via Regione Siciliana, the highway that loops around Palermo, but La Cubana is actually worth a small excursion. Piazza F. Restivo off Via Piemonte. Via Generale Magliocco 15 at Via G. Vaglica. Equally excellent selection of pastries.
