Rainbow's Basement?

About
Located underneath Rainbow's Place through the stairs outside, Rainbow's Basement? is the target of Twilight's experiment on building dungeons, as well as Javis' first scrambler location that twists the dungeon into a larger area than it originally was.

There is a couch found just before entering the B2 area of the dungeon, where the party can recover their HP and MP for free.
