questions and answers

The most frequently asked questions about wedding celebrations at the Hagerbach Test Gallery are answered right here!

Up to 200 people:

With us you may conveniently compose your menus from our banquet brochure. There is a nice selection of served delicacies or even buffet options. Of course, this may also be combined or an individual menu created during a personal consultation.

We cook mainly with Swiss meat and source regional and seasonal ingredients when available.

The service, place settings including tablecloths and napkins as well as the tables and chairs set up by our team according to your wishes are included in the menu price.

Drinks are charged per consumption according to the banquet brochure. We have a small and fine wine selection there. If you would like to bring your favourite wine and have it served, you are welcome to do so at a tap fee of CHF 36 per bottle. This is the exact same margin that we apply to our wine range per bottle.

Caterer Dine&Shine from 200 people:

Dine&Shine is an experienced caterer for events over 200 people and are top equipped for this. Dine&Shine is our preferred partner. However, you are free to choose another professional caterer.

To enable you to cater with external providers, we charge:

  • Room rentals
  • Work on direction
  • Material/Event equipment on demand
  • Personnel costs for supervisory staff

Of course!

In the warm months and in good weather you can enjoy the aperitif in front of the gallery portal or use the front part of the Restaurant Hagerbach for the aperitif. Alternatively, you can hold the aperitif in the depths of the mountain.

We will be happy to show you the possibilities during an on-site visit.

For a successful aperitif, we recommend 2 to 3 delicious appetizers per person to whet your appetite. You will find a selection in our banquet brochure.

When hosting events, it is important to find a balanced time schedule to ensure that all guests have an enjoyable experience. There should be enough time to talk to guests without anyone getting hungry or bored. At the same time, the schedule should be such that the service staff does not have to rush and the dishes can be served at the highest quality.

To accomplish this there are a few principles.

  • From the time the guests enter the room until the first course is served, at least 30 minutes. This gives the guests 15 minutes to find their seats and have a chat on the way there. Likewise, this allows the service 15 minutes for beverage service.
  • At least 45 minutes between courses, and at least 1 hour for the main course. This allows enough time to serve the dish, eat this, clear place settings and refill drinks for the next course.
  • Longer speeches or program blocks are recommended after the main course. It often happens that they last longer than planned and a time delay for the following dessert is easier to handle than for the main course, where meat should be cooked to perfection. So if the main course is served at 8:30 p.m., the block of games or speeches should start at 9:30 or 9:45.
  • For an all-around successful event in our event location, we recommend starting the dancing or bar after dessert. Early start of dancing may lead to neglecting the dessert and guests who do not want to dance will not feel entertained.

The VersuchsStollen Hagerbach is one of the most impressive event locations in Switzerland. The Event-Cavern for example already offers by nature numerous possibilities for individual decorations. Our spotlights can be customized to match your color theme, napkins are available in classic white or color-coordinated. In addition, we can project decorative subjects, movies or slide shows on the walls. For a romantic atmosphere, chair covers with bows are available, carefully assembled by our team.

Our rustic 'hay wagon' can serve as a gift table or part of the buffet, and an old wooden sleigh at the entrance to the hall can be used to elegantly present the seating arrangements. The design possibilities are many.

Get inspired by pictures on our website and arrange a personal meeting on site to find the ideal decoration.

For example, how about a photo box at the front of the restaurant to entertain your guests and capture precious memories?

Event cavern for events up to 200 people:

Since the spring of 2022, we have been working with Winkler Livecom on the technical side. In addition to the decorative technical elements such as wall projections and colored spotlights, we now have great sound and lighting technology, which is also very easy to use. Microphones, projector and screen, amplifiers and loudspeakers as well as stage equipment - everything is available in the Event Cavern. Do you want to dance? In the event cavern there are disco lights which automatically adjust to the music. In addition, there is a disco ball and fog machine - all easily operated from a tablet.

Do you have guests who cannot travel from abroad? With our live streaming technology we can even cover such requirements!

"Glück-auf" cavern for events over 200 people:

The "Glück-auf" cavern is like a blank canvas. The setting is good. Stage elements are available on site. Hanging points for event truss and cabling for the control room is pre-installed by Winkler Livecom. All other technical equipment will be brought by our technical partner after customer agreement for the individual event and installed on site, operated during the event and then professionally dismantled again.

One of the great advantages of a party in our event location in the mountain is the possibility to celebrate late into the night, without regard for other guests or neighbors. In the gallery events are possible until 4 o'clock in the morning, whereby from midnight an extra charge of CHF 220 per commenced hour is calculated.

Bride dancing with guests on the dance floor at a wedding party

In fact, this is extremely rare. Our event cavern is located just 70 meters from the tunnel portal, and most of our tunnel rooms offer enough space that even a truck could fit through. In fact, our spaces are often more spacious than your local supermarket. A helpful clue: If your guests can drive through a highway tunnel without any problems, they are in good hands with us!

Our heated event spaces, including the Event Cavern and our seminar rooms, allow you and your guests to dress appropriately for your celebration. If you have activities planned outside of these rooms in the Gallery, we recommend sturdy shoes and a jacket, as it is usually about 15 degrees there, the terrain is occasionally uneven, and the ground is not as clean as in our rooms.

"Glück auf" cavern

Our largest cavern does not have floor heating and is therefore a bit more difficult to heat. Normally, the temperature there during the event is around 19 to 20 degrees Celsius. Therefore, we recommend wearing long-sleeved clothing and making sure you have good shoes, as the cold can often come up from the floor.

Smoking is prohibited in the restaurant, the event rooms and the seminar rooms. However, smoking is permitted in the main gallery area. This means that we can place a couple of smoking tables between the event hall and the toilet facilities so that guests can easily step out and enjoy a cigarette along with a drink without getting rained on.
