I will be visiting Kyoto, Tokyo and Hakone with my family. We are all food lovers and adventurous eaters, with one giant exception: My 13 year old son is the fussiest, and most limited eater on the planet (and allergic to some things). Does anyone have suggestions for both lunches and dinners that would appeal to the food lovers, but also take into account the 13 year old? (He doesn't eat any fish, red meat, dairy) , We are open to local dives as well as big splurges. Many thanks for your thoughts.
