Ask what the fishing boats supplied before ordering at one of the harbour's very few dependable dinner tables
On Agathonisi, a taverna is part restaurant and part practical infrastructure. Glaros faces the harbour and is one of only a few choices, so availability matters more than chasing an elaborate menu. Ask what was cooked that day, confirm fish weight and price and order local vegetable dishes alongside seafood.
Reserve the first evening before travelling and confirm opening outside peak summer. Cash is useful, allergies should be stated clearly and ferry disruption may affect supplies. A patient, shared meal fits the island better than expecting rapid resort service.
