Mein Haus am See rents its rooms for company events, Christmas parties, weddings and private celebrations for 50 to 400 guests. It is a bar, café and club at Brunnenstraße 197-198, at Rosenthaler Platz in Berlin Mitte. The basement club, called Cosmic Kaspar, can be booked exclusively, with its own bar, lounge, restrooms and event technology.
Seminars and company events
The venue is made for evenings rather than working days. Company events, Christmas parties and year-end parties are the core of the offer. The equipment listed for hire includes a DJ system, a lighting system, a projector, a screen and microphones, as well as a cloakroom, a private bar and separate restrooms. Cleaning and the use of the technology are part of the rental.
For Christmas parties, the room can be booked from 40 guests, seven days a week. On Mondays, Tuesdays and Wednesdays in November and December, an all-inclusive package covers six hours of exclusive use, a drinks flat rate for all guests, a festive finger food buffet with vegan options, the sound system, the projector, free Wi-Fi, bar staff, door control and final cleaning.
Weddings and receptions
The venue lists weddings, engagement parties, bachelor and bachelorette parties, graduation balls, birthdays and other private celebrations among the events it hosts. The basement club is rented as a whole, so the party has the lounge, the dance floor and the bar to itself. Extras can be added, such as a DJ with sound and lighting for a set number of hours, or a photo booth.
Rooms and capacities
The venue states an event room for 50 to 400 guests. Two areas matter for a booking. The ground-floor bar and café, Mein Haus am See, takes table reservations of 2 to 15 people online. The basement club, Cosmic Kaspar, is the part rented as a private event space. Group reservations of 15 or more, and every event rental, are handled by email only. The site does not give a separate capacity for the basement.
Catering
Drinks come from the venue. Hosts choose between a drinks revenue guarantee, where guests order from the menu and the host or the guests pay, and a drinks flat rate per person for a fixed number of hours, in four tiers from draft beer and soft drinks to an open bar. Food comes from the venue's own caterer, which provides finger food buffets, including vegan dishes at Christmas.
History and setting
The venue is one of several bars and clubs run by the same team in Berlin. It describes itself as neither a bar nor a club but something between the two. It opens every day from the late afternoon, and its location at Rosenthaler Platz places it between Mitte and Prenzlauer Berg.
Getting there
The nearest U-Bahn station is Rosenthaler Platz. Trams M1 and 12 and buses 142 and N8 (night) also serve the area, and there is a taxi rank at Rosenthaler Platz.
