My fam are mostly vegetarian/pescatarian (I'm not). But Kyotofu Fujino was completely amazing: https://maps.app.goo.gl/hF8b7VPdotVbGPzM7 It's a tofu specialty restaurant that we went for lunch before taking train back to Tokyo. This place had long been recommended to me and now I totally regret not going there during my previous visits there.
Not a specific recommendation but we've always found really worthwhile izakaya, yakitori, soba, etc places near our lodging.
And as much as the temple/shrine/institution is the attraction, the supporting snack/restaurant/trinket shops surrounding the attraction are worth wandering around in, Arashiyama, Kiyomizu-dera, etc have fun supporting food/shopping areas.
And if you don't have time to go to a hot spring, a local bath house is fun too.
