YIRI established the culinary brand Solar Café in 2010. The stylishly decorated restaurants offer foods free from artificial flavors or additives, and insist on using seasonal, fresh, and healthy ingredients from local farms wherever possible. The brand spirit revolves around eco-friendliness, healthy living, and organic lifestyle. The first restaurant was opened in the Tianmu area, attracting much attention for its emphasis on natural ingredients. Since then, the café has opened 3 more branches, each with its own unique décor and style. The latest opening on Zhongshan street（2015）offers a more traditional Taiwanese-style Hot Pot cuisine, further expanding and mixing culinary tastes.
