Every morning, local farmers from across Cephalonia set up stalls along the Argostoli waterfront esplanade, selling vegetables, fruit, honey, olive oil, local cheese, and bottles of Robola wine. The market breaks up by mid-morning, so arrive early. This is where you see Argostoli functioning as a working capital rather than a tourist town: farmers who've driven down from hillside villages, fishermen selling the night's catch, and locals arguing good-naturedly over tomato prices.
The esplanade itself is pleasant at any time of day — cafes with outdoor tables overlook the lagoon and the surrounding hills, and the waterfront is busy with boats. The market gives it an extra dimension at breakfast time. If you're heading to a beach or a day trip, this is a good place to stock up on provisions.
