I spent 4 weeks in Kyoto, and tried nearly every vegetarian restaurant there. Kairasu was the last place I went, and I was sad that I didn't go there first. The space is so peaceful and relaxing, and the couple that run it are so friendly and sweet, and speak just enough English to make you feel understood. The food was excellent, with such incredible attention to detail. The lunch set is the best deal, and the dessert (banana parfait) was excellent. We also bought one of all their cookies to eat the next day. If you want fancy and flashy, go to Cafe Proverbs. If you want to relax, and feel the vibe of Kyoto, go here.
