How do I identify restaurants that offer excellent training/education? I considered looking at the number of chefs that learned at a certain restaurant and afterwards achieved a Michelin star or won prices etc. However, I could not find any database for this kind of information. Does such a database exist? If yes, would it be a good approach? I don't know many people in the culinary world who could recommend a suitable restaurant to me. As an alternative, is there some kind of forum with this kind of expertise? Maybe the chat of this site? Or is there a ranking of restaurants with regard to their educational quality? If it matters, I am interested in restaurants in Europe, especially in Germany. TLDR: What are strategies to identify restaurants where you will learn as much as possible? Edit Based on the advice from the comments some additional information: I don't have experience as a chef until now and my goal is to learn as much as possible within two or three years. I don't necessarily need a formal degree, but ideally I would also obtain one. 
There is a forum: eGullet, which is an online message board for culinary professionals. Try their Culinary Classifieds for staging advertisements, and Restaurant Life to ask about advice on how to find a good stage.
