The chef will lead hands-on coaching to help locally rooted restaurants that face acute pressure and uncertainty.

Overview

  • RTL announced on Wednesday that Christian Rach will be back as 'Der Restauranttester', with filming starting in September 2026 and new episodes slated to air from spring 2027.
  • Rach says he plans to visit neighborhood restaurants, listen to owners, give blunt operational and menu advice, and work with them to develop realistic plans for survival.
  • RTL content chief Inga Leschek praised Rach as uniquely suited to the role, saying his track record of direct, practical interventions motivated the timing of the revival.
  • The broadcaster has not disclosed how many episodes will be produced or which restaurants will be featured, leaving the series’ scope and geographic focus open.
  • The format originally ran from 2005 until its 2017 cancellation, shaped a coaching-doku TV genre and won multiple awards, and Rach’s return follows his long TV presence including 103 appearances as a juror on 'Grill den Henssler' before his 2025 exit.
