Okonomiyaki - "Japanese pizza"

Okonomiyaki (お好み焼き) literally means “grilled as you like it” in Japanese. I saw this being made on a UK food show featuring The Hairy Bikers during a visit to Japan.
Looked like my kind of food so had a go at making it.
I used the recipe from norecipes.com and while it lacked many of the more exotic ingredients such as the katsuobushi or nagaimo I think it turned out reasonably well.
With no Japanese mayo I just used Hellmans and I had read that okonomiyaki sauce is very similar to Worcestershire sauce so just used that in its place.
