The Overthere (bar)
From the Super Mario Wiki
The Overthere is a coffee bar (described in-game as a "beveragarium") found on the first basement floor of Flopside, in the game Super Paper Mario. It is much like The Underwhere bar, found in the same place in Flipside, but The Overthere serves coffee while its counterpart serves milk. Both are named after the realms of the dead visited in Super Paper Mario, The Overthere and The Underwhere. The milk bar's owner is Carson, who tells amusing stories concerning subjects of the game for ten coins, as does the owner of the other bar, Garson.
Like at The Underwhere bar, Mario can go through the back wall via flipping; however, instead of a Warp Pipe, there are two chests. The first one contains the Golden Card, an item required to play a secret mini-game in the Flipside Arcade. The second chest contains a Cooking Disk.
