Nagal Residence

From Memory Alpha, the free Star Trek reference

The Nagal Residence is the gigantic, lavishly appointed home of the Ferengi Grand Nagus. It is located in the capital city of Ferenginar, with a view of the Tower of Commerce. It is said that even the Waste extraction fixtures were plated with latinum. Quark planned to replace them with solid latinum fixtures when he thought he was going to become the next Nagus in 2375.
