I've always wanted to try out Japanese hot dogs and was excited to hear that it finally arrived in Montreal!
I finally tried it out with a friend for lunch, and luckily it was not busy when we got there. We ordered the Kaarage hot dog combo, which doesn't come with a wiener but the fried chicken, and their takoyaki. The food was brought to us pretty quick, about 5mins after we took our seats after ordering. The karaage hot dog was good, however, the pieces of chicken were a little small so it felt like there was more bun than meat. I would have also loved it more if their buns were toasted or warm though! As for their potato side, homemade potato chips with toppings, and their takoyaki, they tasted pretty good!
Although I wasn't too impressed with their karaage hot dog, I would definitely come back and try their other menu items (actual hot dogs and sushi burgers)! Their prices were not cheap (the karaage hot dog combo came up to ~14$), but is still worth it depending on what you get.
