Shelter Beneath the Mundane by drvsilla.

Slash.

I’ve decided that I quite like amnesia fic, which is what I thought this was. But it turned out to be Dean in hell fic, that is a story where Dean goes to hell and Sam gets him out. There’s not a lot of hot sex here, but there is intelligent storycrafting, whereby Dean suffers through the fires of hell by imagining he’s still got a purpose. And that is, running a little breakfast place for all those people he was unable to save, and who are also in hell. I quite liked the concept, because it was original and it FITS with how Dean sees himself. He’s one of those who does what must be done. He’s very duty bound, and his way of controlling the pain of hellfire is by doing his duty. Lovely.

Excerpt:

Dean began the day’s routine, same as yesterday, same as tomorrow would follow. Coffee first, left to percolate and fill the huge silver urns that lined the back counter; one of them gurgled and he thumped it with the heel of his hand, nodded in satisfaction when it groaned and steadied on. Grill warmed and eggs set next to it for omelets or sunnysides, bacon laid down to pop while it cooked, bread and muffins and rolls in case someone wanted it as a sandwich. Everything else was where it should be – plenty of fruit in the basket next to the register, cinnamon rolls still fresh enough to serve, mints in small tins just because.
