I would never recommend this place to my friends. What you get here is way overpriced so-called "Japanese" food of mediocre quality and tiny quantity.
I had the misfortune of going there because someone booked this place for a friend's birthday. It took almost an hour for the food to arrive after we placed the order, and when it did arrive, I couldn't believe how small the portion was. There was nothing special about the taste either, you can have similar stuff somewhere else for one third of the cost.
By the end of it, my wallet was $35 lighter, and I left the restaurant still feeling hungry.
Only in Montreal can Bistro Isakaya survive, it would have gone out of business many times over had it opened doors in Toronto, where many better and more reasonably priced Japanese restaurants are located.
