I'm not from Montreal but always stop by Kinka Izakaya for lunch whenever I am in town
-for singles, you can eat at the counter
-staff is very friendly; all the employees say goodbye to you when you leave in traditional Japanese style
-I usually get the lunch special: Ramen (Pork) and Rice Plate (fried vegetable); it is great value. The rice plate is okay but the ramen broth and noodles are delicious. The pork is a little too lean for my taste but the broth makes up for it
-bathrooms are clean and have listerine rinse
-about a 5 minute walk from the Guy Concordia metro station
Good place for lunch especially if you like Ramen
