What on earth is okonomiyaki? Nami, a Japanese cook based in San Francisco at justonecookbook.com defines it thus:
Okonomiyaki (literally means ‘grilled as you like it’) is a savory version of Japanese pancake, made with flour, eggs, shredded cabbage, meat/ protein and topped with a variety of condiments. Better known as ‘Japanese pizza’ in the US, you can definitely prepare the filling and toppings however you like it. A wonderful way to use up your leftovers!
In Chicago, Stephaine Izard of Girl and the Goat fame serves a marvelous okonomiyaki, certified to taste authentic by our younger daughter who’s been to Japan, at her Little Goat Diner. The first time I ate there, my dish was overwhelmingly voted the best of the three dishes, according to the other two diners. This time, we all ordered okonomiyaki (with a giant, homemade cinnamon roll as our appetizer!) and all agreed it was amazingly delicious. That’s a soft-yoked egg on top, ready to meltingly join the rest of the dish, which includes eggs, cabbage, pork belly, scallion, and tasty Japanese mayonnaise.

You can get Stephanie’s recipe and even watch her make okonomiyaki by clicking here. If you don’t feel like making it, you won’t be sorry to find a restaurant that serves it. If you’re in the Chicago area, make a reservation at Little Goat Diner. If not everyone wants to try this, they have plenty other delicious choices. Here’s a link to the diner menu, from which you can also access the bakery and coffeehouse menus and other of Stephanie’s restaurants.

There are other restaurants in the Chicago area serving okonomiyaki, including one that just opened and is dedicated to various styles of this dish, but I haven’t tried any of them, so I’ll stick with what I know and perhaps have a chance to try another place before we move.
January 21 update. One of my online friends tried this dish, putting her own spin on it and making it more user-friendly. Take a peek and see what you think (and what her husband thought): Down-home Okonomiyaki.
