The Roost
From Wild World Wiki
The Roost is the cafe run by Brewster the pigeon. It's in the downstairs section of the Museum. You can get a cup of freshly-brewed coffee for 200 bells, or just sit and relax.
K.K. Slider will drop into The Roost every Friday night at 7:30pm, and from eight o'clock onwards he'll take requests for songs.
Occasionally Kapp'n will drop in for a cup of coffee and a chat.
