The coffee is delicious, and the staff is friendly. The only downside is the shop: the photos don't accurately reflect what you'll find on Via Capo Linaro, and perhaps the selection isn't the best either. When you arrive, the lady tells you the store is on Via Carlo del Greco, and she'll try to find a solution based on your needs.
I met Donato, the manager and owner, several years ago. Knowledgeable and helpful, he recommended a coffee machine that I still use today—efficient yet affordable. He also recommended Spartacus coffee capsules, as the ones I'd tried previously were either too weak or extremely strong. The shop also sells sweet and savory products, jams, and more, along with a wide selection of coffees and coffee machines.
