The Kitchen is a room in the Gloomy Manor in the game Luigi's Mansion: Dark Moon. It is located near the Library and the Dining Room. It is where Luigi first fight Greenie that wield weapons and defensive objects.
During A-3: Quiet Please!, Luigi must head through the Kitchen in order to get into the Library. However, he is stopped by Greenies that wear pots and pans and carry rolling pins. Luigi vacuums up the Greenies and heads into the Library. Luigi fights Hiders in this room as well.
A Gem can also be found here. Luigi must simply open the fridge and vacuum the frozen Gem. He must then carry over to the nearby stove and melt it.
