Cheng Ji Taipei 101 is a French pastry shop on the B1 floor of Taipei 101 in Xinyi District, Taipei. It sells fresh chocolate brownies and caramel cheesecake. The brownies come as eight pieces dusted with cocoa powder and include a fork. A notice advises eating them within 30 minutes of purchase or storing them frozen, which gives them an ice cream-like texture; the caramel cheesecake and pistachio tiramisu are on the sweet side.
