Osaka prides itself for the okonomiyaki, Hiroshima as well, I prefer the Hiroshima version, not sure why as it is equally fat, greasy and unhealthy!! but it is fun I like to go to Goemon, fun place, not touristic, small, lively, fun try it!
I was lucky enough to be in Hiroshima when the Carps win the central league. What a unique vibrant city and what an atmosphere, the citizens went on a mega gigantic high touch evening, the city became noisy and people were celebrating all evening, it is difficult to describe it, watch it!!
