The RF kelleren is a faculty association affiliated with the Faculty of Mathematics and Natural Sciences at the University of Oslo. The association is open to all students, regardless of field of study, and offers an inclusive environment for socializing. Located in the basement of Vilhelm Bjerknes' house, the RF basement has a student-run café and bar that acts as a meeting point for students.
In addition to serving food and drink, the RF cellar organizes various social and cultural activities. This gives students the opportunity to participate in an active student community and create memorable experiences during their studies. The association thus contributes to a varied and engaging student life at Blindern.
