Dining out with kids can be challenging in Tokyo. One tip is to look for restaurants that have koshitsu, private rooms. You can then close the doors and the kids can play in the private room without disturbing the other diners. Adults can enjoy some conversation without worrying about the kids. Koshitsu are also nice when getting together with family or friends and you’d like some privacy.
Mimiu near Shinjuku station has several private rooms exactly for this occasion. It is a popular restaurant with families, so best to book a private room in advance. Be sure to inquire about seating. Some koshitsu have tables and chairs while others are tatami mat rooms with low tables. Ideally there will be a hole under the table with a sunken floor, called horigotatsu. These can be surprisingly comfortable.
Some other tips when using a tatami room. You’ll be asked to take your shoes off. If you need to use the rest room while dining use the sandals that are set near the room. Most koshitsu will have a bell to ring when you need something.
Mimiu has a few set lunches to choose from, starting at about 2,200 JPY. Above is one of the lunch sets. The food was not spectacular, but was passable. I was surprised that they did not have options for the kids. The set menu was definitely too much food to order another lunch for the kids, so we shared.
This location is conveniently located a minute or two from Shinjuku station. Mimiu has a few other locations in the city. When we reserved the room we were told that there was a two-hour limit.
