Maison Du Japon takes up a huge space in the corner of Woodbine and John. In addition to having a huge dining room, they actually have an event room in the back in case you are hosting a private party/event. There are screens in the room as well as a karaoke machine (I think?).
I've been coming here once in a while for years now. Back in the day (before the days of iPad menus), Maison was pretty good and probably one of my favourites because they had a huge variety. Nowadays, there are many other options for all you can eat, with amazing quality for a similar price, and Maison just doesn't stand out anymore.
If you happen to be coming here regardless, their arctic roll (available all day) is actually really good and isn't heavily loaded with rice.
