Native speaker’s answer

A "themed restaurant" is a restaurant that has a specific topic or a specific atmosphere. These restaurants' decorations, food, and even staff will be dressed up to match the theme for the restaurant. Themed restaurants are meant to create a fun and unique experience for customers. For example, the Rain Forest Cafe is a themed restaurant in the United States that makes you feel like you are eating in the rainforest. Maid Cafes are popular in Japan because their waitresses are dressed as maids and these cafes are meant to bring a cute and fun experience for the customers.
