If you're getting "temple fatigue" in Kyoto (it happens to the best of us), Nishiki Market is the perfect palate cleanser. Stretching for five blocks, this place is literally called "Kyoto's Kitchen" and absolutely lives up to the name. Just imagine a whole street dedicated to everything food - from stuff you recognize to things you'll need Google to identify!
What makes it fun is how you can graze your way through centuries of Kyoto food culture one sample at a time. Want to try weird pickles you've never heard of? They've got them. Curious about those Japanese sweets you keep seeing everywhere? You can taste test here. Looking for some cooking implements to take home? Good luck fitting that traditional knife set in your carry-on!
Pro tip: Don't eat before you come - there are too many tasty things to try. Also, while it can get crowded (what good food spot in Japan doesn't?), this is one place where the crowds are part of the experience. Just go with the flow and let your taste buds lead the way!
