Reason for existence, Reson Detro

The term "reason d'etre" means the reason for existence. In Jonathan Safran Foer's book, "Extremely Loud and Incredibly Close," the main character talks about his reason d'etre! He talks about what he likes and his reason for existence. I was entranced when I saw the cafe's introduction that said, "I love eating and cooking. My reason d'etre is my life as a pastry chef." How appealing is it that he created a cafe as a place to talk about the reason for existence and reflect on himself? It was even more impressive because it was a place where you could enjoy delicious desserts and drinks! 📍Vanilla Egg 7,000 won Hojicha Latte 6,500 won 📍Reson d'etre Cafe, 67-2, Jahamun-ro 7-gil, Jongno-gu, Seoul #InstaHotPlace #HotPlaceCertificationShot #HotCafe #SeoulCafe #SeoulTravel
