Salon 3SEIN can be hired exclusively for company parties, conferences, seminars, workshops, weddings and birthdays, for up to 140 guests in about 170 m². It is a tapas and wine bar with an event salon at Große Bleiche 60-62 in Mainz, in the government district of the capital of Rhineland-Palatinate, run by Norbert Schön and Maribel Arnau.
Seminars and company events
For a workshop, seminar or conference, the salon is rented as a whole, so a team has the room and the bar to itself. The layout is modular: tables can be grouped for working sessions, set in rows for a talk or cleared for a standing reception. Modern technical equipment is part of the rental, and catering can run through the day, from breaks to a dinner after the last session. The salon also suits a company party or a team evening, because the same room moves from a meeting setup to a bar evening with tapas and wine without a change of venue.
Weddings and receptions
Weddings and birthdays are among the private events the salon takes. A party of up to 140 guests has the whole room, and in summer the large outdoor area adds space for drinks or a reception in the open air. The catering is adapted to each celebration.
Rooms and capacities
The salon covers about 170 m² and holds up to 140 people. Its layout can be changed for each event. A long communal table, large enough to seat a big family, is a fixture of the room and suits a shared dinner where guests who do not know each other end up talking. In summer, the large outdoor area can be added to a booking.
Catering
3SEIN makes its own tapas, small dishes meant for a light appetite, and offers high-quality catering adapted to the event. Wine is central to the place: the team cites a Food & Wine feature that listed it among the best wine bars in the world. For regular service, the bar opens Wednesday and Thursday from 5 p.m. to 1 a.m. and Friday and Saturday from 5 p.m. to 2 a.m., with the kitchen serving warm food from 5 p.m. to 11 p.m.
History and setting
The owners built the salon around conversation, good food and good drinks. Beyond private hire, it runs a cultural program that shows how the room works with an audience: a monthly pub quiz, the Wilde Worte Mainz poetry slam once a month, and a milonga on the fourth Sunday of each month, held with the association tango argentino in mainz. The government district places the salon in central Mainz, within reach of the Rhine and the old town.
Getting there
The address is Große Bleiche 60-62, 55116 Mainz. From Mainz Hauptbahnhof, several bus lines stop at Bauhofstraße / Landesmuseum, close to the salon. Frankfurt Airport is about 30 km away, with direct trains to Mainz Hauptbahnhof.
