The Resi was the nickname of a vast, luxurious dance-hall called the Residenz-Casino at the Blumenstraße 10 in Berlin, Germany.
Rohrpost at the Restaurant Resi Casino
The Resi's most talked about feature were private telephones fixed to tables and various stations around the venue, where customers could contact other tables or flirt anonymously with other guests.
One could also choose from a menu of 135 gift items and have them sent to other guests via a pneumatic tube system (Rohrpost) situated between the tables.
Postcard, Resi-Casino Berlin
Jeder einmal in Berlin, jeder einmal in "Resi"!
Printed at the back of the postcard:
"Das Ballhaus der Technik"
Im "Resi-Casino" würde nicht nür das Tischtelefon im Ballsaal und die Tischrohrpost erdacht, im "Resi" sah man auch zuerst die Wasser- und Lichtwunder.
