You can find a list of restaurants near Kiyomizudera on the following website. As you said, there a lot of places to try sweets on Kiyomizuzaka, the street leading up to the temple, so I think you'll become pretty full (I did) and might want to consider having dinner near your hotel instead. Anyway, below is the website.
Hi. I'm planning to end my day of sightseeing near Kiyomizudera. I hear that the street leading up to the temple has shops selling sweets and snacks, so I intend to try some, but after seeing the temple I'd like to have a light dinner somewhere. Any nice restaurants nearby? Thank you.
