Semeli

Semeli is a seafront bar in Little Venice, open since 2005, with water views and a lively atmosphere in the evening. A resident DJ plays classic R&B and mainstream tunes, which gives it more of a dance-floor feel than the quieter sunset bars next door. Greeka calls it one of the funkiest bars in Mykonos.

Google lists it as open from midday to 05:00, so it can cover a late sunset and the small hours, but that listing is undated and the bar is seasonal, so check before you go. Prices are not published, and guides rate it in the upper price band. Not for you if you want a quiet table by the water after dark: when the DJ starts, the volume goes up.
