Osaka is Japan's kitchen and knows it: kuidaore means eat until you drop and locals do. Dotonbori is the theater; the actual best takoyaki is at Wanaka Sennichimae, best okonomiyaki at Mizuno, and best kushikatsu at Daruma with the never-double-dip rule. Osakans are loud by Japanese standards and will actually talk to strangers. Skip the tourist Kani Doraku crab; go to Kuromon Ichiba market for tuna sashimi carved in front of you. Escalators stand on right, opposite Tokyo.
