You can enjoy seasonal vegetables, meat, seafood with reasonable price. You can enjoy each kushiage with salt, their special dipping source, lemon or miso-dip. They have table-seating and also counter-seating. The advantage of counter-seating is that you can see the chef fry the kushikatsu fresh right in front of you.
About 40 minutes by subway from central Tokyo, not many travelers but always full of local people.
You should make reservation especially on weekends.
