Now I'm in Osaka visiting my sister.
We stumbled across the Negibijintei (Beautiful Onion Woman) okonomiyaki restaurant while searching for some rice for lunch. This place is near the Umeda train station and is amidst a one of those restaurant floors in a multi-level transportation/shopping complex. [corrected "Senri Chuo" to "Umeda" 4 Sept 2005]
I ordered a standard okonomiyaki and my sister chose the seafood one. According to my expert sister, this place makes okonomiyaki with a lot more spring onions than usual. The fritatas come pre-made and you warm them on a hot plate set in the middle of your table. You can brush a sweet soy sauce and sprinkle bonito flakes on top while the plate keeps it warm until you're ready to eat it. Then you use the little fish slice to cut a bit off and eat it.
