Isekai de Café o Kaiten Shimashita.

Kurokawa Lisa is an ordinary office worker, who has practiced lots of cooking while living alone. One day, she wakes up in another world, with a concerned little spirit hovering over her! She has apparently been transported to a magical, spirit-filled realm by the will of the goddess, and there is no known way for her to go back. She is taken in by a wealthy couple, and they and her new spirit helper treat her with nothing but kindness. There is one problem, however – the food in this magical world is gross! Lisa insists on helping the household cooking staff prepare a traditional meal from her world, and it is a big hit with her hosts. Soon Lisa knows what she should do in this new world; she should open a cafe and treat everyone to delicious food! https://mechacomic.jp/books/156460
