The Scala Days lunches will be served at the "Parmentier", on-site at EPFL.

The Parmentier can be easily reached from the Polydôme by walking towards the large concrete stairs and getting up to the last floor. You will see some table tennis tables and, to their left, an orange door marked "AM". Just reach that door, without entering; on your right you will see a passage that leads directly to the Parmentier.
