Best used room in the house

From Dicken’s Bleak House:

“Sit down, my dear,” said Mr Jarndyce. “This, you must know, is the growlery. When I am out of humour, I come and growl here.”

“You must be here very seldom, sir,” said I.

“O, you don’t know me!” he returned. “When I am deceived or disappointed in — the wind, and it’s Easterly, I take refuge here. The Growlery is the best used room in the house. You are not aware of half my humours yet. My dear, how you are trembling!”

Hmm, the growlery might be the best alternative name for the internet yet.
