My travel rule is to eat local. (ok, for the really long trip where I am worn down I will seek out something from home)

But I see travel as the perfect time to try new things, so I like to eat what the locals do. Indian food in London, Brazilian and Japanese in Amsterdam
I do my research and find out what are the best regional dishes, and go for those. In Europe I always luck out as each area has specialty beers and cheese. I am a historian, so am trying to document these trends.
