Definitely a current favorite for ramen in Montreal.
Waiting time - Of the times I've been here, I only waited once. On weekdays it seems reasonably easy to get a table within 5 minutes of arriving.
Food - After having tried multiple items on the menu, I definitely opt for the original ramen with pork broth and thin noodles. If you go for anything with fried chicken, I don't think the spicy one is as good as the original since they really cover it in too much sauce. The portions are also pretty large, don't expect to eat more than a bowl of ramen.
Service - Super fast. The last time I was there we got our food before water even came, probably less than 5 minutes after ordering. They are definitely polite as well.
Price - Reasonable. Expect less than 20 per head if you're only there for ramen, otherwise a little bit more.
