Star Bank
From the Super Mario Wiki
The Star Bank is a house in Mario Party 6 where players trade stars for prizes and other valuables, such as new difficulty levels, rare mini-games, and the playable character, Toadette. It is not a part of any board in the game, but is accessed in the area where 1-player or multiplayer mode is located. It is always open, but the Brighton and Twila will immediately tell the player that they do not have enough stars to buy anything if the player doesn't have any stars.
