You guys have no idea what's down there

From the guardian.co.uk:

Police in Paris have discovered a fully equipped cinema-cum-restaurant in a large and previously uncharted cavern underneath the capital's chic 16th arrondissement.

Patrick Alk, a photographer who has published a book on the urban underground exploration movement and claims to be close to the group, told RTL radio the cavern's discovery was "a shame, but not the end of the world". There were "a dozen more where that one came from," he said. "You guys have no idea what's down there."
