The neighborhood restaurant is really a hangout for locals. The sushi quality is generally excellent but lacking the more exotic, the cook tends to be a neighbor, conversation is welcome and the beer is cold. Quite often, you'll be given free samples of anything unusual such as an unusual fish, a new recipe, a new brand of sake, or if your opinion about some quality of the cooking is wanted.

Those in the bar/shopping districts are really fast food restaurants for the most part or a place to bring a date or grab a quick bite to eat. Most people don't know each other and often the sushi is served in little colored plates that the hostess counts when you leave to determine your bill. They often use a gimmick to deliver the sushi such as trains or boats carrying the sushi. Don't expect much conversation or any samples unless you are a friend of the owner.

And, finally, nice restaurants are VERY nice. Unless it is in a tourist area, you should be chaperoned by a local as there is certain etiquette to observe. The bill could induce heart failure among the unsuspecting. The food is exquisite. Most Japanese will use a business account to pay for the meal while hosting a 'business' guest. Expect to hear some drunk Japanese singing in the room next door. In these situations, much fun is had by all.

Just my opinion.
