In the location's words:

Rossini in Wuppertal is a chic restaurant in the Historische Stadthalle, where you can not only eat delicious food, but also take part in cool events.

Rossini is also open before and after events in the Stadthalle, so you can round off your concert visit with a good meal.

The exact opening times vary depending on the event, so it's best to check the website beforehand.

Have fun discovering and enjoying!
