"For anyone who is curious about Japanese okonomiyaki, Gaijin is the place to go. This West Loop spot serves both Osaka and Hiroshima-style okonomiyaki (the difference is that in Hiroshima, the ingredients are layered instead of mixed together and served with yakisoba noodles) with a wide choice of fillings, plus negiyaki, stuffed with scallions instead of cabbage." - aimee.levitt
