Salon de Thé de Marnie (translated to English as Marnie's Tea Room) was a pâtisserie, formerly The Teahouse until Marnie Nightingale purchased the building following the death of the previous owner, Stuart Sumner. Marnie hired her grandchildren, Juliet and Romeo, to work at the pâtisserie, along with other unknown employees as well as Scott Drinkwell. Scott eventually quit, and by late 2021 only the Nightingales (and Juliet's mother Donna-Marie Quinn) were working at the pâtisserie.
In January 2022, the building exploded during the "Dee Valley Heroes" event. The disaster claimed the lives of Marnie, Sylver McQueen and Celeste Faroe.
