Mushroom-King it is the same with Chinese. China is so big and has so different foods to offer, but in Europe all of the Chinese restaurants are the same.
Some years ago in Lisbon were running a couple of illegal Chinese restaurants (more like apartments where families from China lives, no English, no really Portuguese language so much and literally families with all kids ect. ) and all dishes were so good and different from typical restaurants.
It is interesting how the geography and climate effects wee effecting our diets, but nowadays we really eat so much less local foods.
