As we've mentioned, Tinos is a place of pilgrimage, and there's less nightlife here than on many islands; as always on the islands, places that are hot one season are often gone the next. Two sweets shops, Epilekto and Meskiles (fantastic loukoumades with ice cream), both on the waterfront, stay open late.
In the streets beside restaurant row, where Palaia Pallada, Metaxi Mas, and Aithrio are located, there is a clutch of bars, with music, TV, and sometimes dancing, including Koursaros, Kaktos, Volto, and Syvilla, and, on the road toward Kiona, Paradise. If you want a late-night (or early morning) coffee, try lecaffe, on the harborfront; instead of a cup, this place brings you a full pot of French filtered coffee. If you want to check your e-mail while you drink your coffee, try Symposio, which bills itself as a cafe/bar/restaurant. If you walk on the main road at night, watch out for the kamikaze motorcyclists.
