About the place

The restaurant belongs to the four-star Hotel On Plonge Junior, on the lakeshore about 300 metres from the beach, in the Neptun jetty area. The menu is built around fish and seafood, and it serves breakfast, lunch and dinner.

Reviews keep mentioning the view over the lake and the food; the restaurant also hosts celebration dinners. Google shows daily hours from 10 to 22:30, until 23 on Fridays and Saturdays, and the hotel takes bookings for December too.

Good to know

  • Come towards evening: the lake lies west of the resort and the sun sets over the water.
  • At weekends and on summer evenings, call ahead to book a table.
  • Aqua Magic and the gondola's Perla station are about 200 metres away.
