Where can you get the most authentic Japanese food?

I've tried:

• susuru: just noodles lol

• Sando: they mainly focus on burgers and fries they are too oily for me.

• sushi shop: just sushi, very few choice for other Japanese foods. Also definitely made by non Japanese guys.

• mikado: really enjoyed their fried pumpkins,steamed salmon, vegetables and mochi. Made by a real Japanese cook.

So far only Mikado has some variety. It feels like when people think of Japanese food, they either think about a bowl of noodles or sushi or raw salmon.

Can anyone recommend Japanese eateries with a bit of variety?
