This is one of the food that represents Osaka - Okonomiyaki (お好み焼き), which is like a cabbage pancake fried over a Teppan (Hot plate). Though the cooking method is the same, there are many kinds of fillings and sauces you can choose from. I went to a shop in Namba with one of my taiwanese friend (Who discontinued her studies and went back to Taiwan) and she was saying that this shop has been around for decades and their cooking style are a bit different from other shops. So let take a peek at their making process...

Osaka Botejyu (大阪ぼてぢゅう)
Making process of a Okonomiyaki

A cabbage mixture is placed on the Teppan as base, and the shrimp on top.

Next, the bacons are placed in, which the cabbage mixture comes in again.

Spreading it evenly, to make sure it looks round & (yummy)

Last but not the least, an egg is beaten on the top to serve as the crust. Please note that in other shops, eggs are usually not added in. That is why we called this shop a bit of special. Served with shop specialty sweet sauce and Mayonnaise.
Motsunabe (もつ鍋) is another Japanese-style hot pot similar to Shabu shabu (しゃぶしゃぶ), with the main difference in ingredients, which are beef or pork offal. The soup is put to boil with the offal, together with vegetables to complete the dish.

The taste ? It is like eating chewing gum but in the end part, you would need to force it down your throat. In order to smoother your throat, best is to down it with a beer ! It might not be as bad as I have described though, but for those who hates or dare not eat offal, you have just missed a japanese cuisine.
As mentioned by one of my teachers, Motsunabe (もつ鍋) was popular among normal salary men because it was inexpensive. Normally these guys would gather together after work, where they will start to eat and drink the night away ...
