Nihonkai - One of my favorite choice of Japanese restaurant. I believe this is also one of the family friendly restaurant, as they have variety of choices (Set Lunch / Set Dinner), big portion and price is very reasonable. Ingredients are fresh too.
For example, normally salmon set comes with 1 slice of salmon, rice, soup, appetizer and steamed egg will cost around RM 25, but here, you can get 2 slices of salmon with cheaper price.
My first visit was years ago with my friends (birthday celebration) at Old Klang Road, you can book a room with them if there's many of you. It's better to make a call to make your booking if you are planning to go during weekend / public holiday / special occasion.
For their branch in Sunway Mentari, normally I will walk in for dinner without booking, but have to be early, eg 6pm...after 7pm will be hard due to limited seats.
