Palermo street fare is good anywhere you have it, but it’s especially savory in this atmospheric, marble-floored institution founded in 1834. If you’ve shied away from buying a panino con la milza (bread roll stuffed with slices of boiled spleen and melted cheese) from a street vendor, you might want to jump in and try the delicious specialty here. You can also snack or lunch on panelle (deep-fried chickpea fritters), arancini di riso (rice balls stuffed with tomatoes and peas or mozzarella), focaccia farcita (flat pizza with fillings), or other sandwiches, curtly dispensed from a busy counter.
