This is probably one of the busiest ramen place in Toronto. I visited them on a Friday night. Like others mentioned, we also had to wait 10 mins in the cold to get seated.
I ordered a Spicy Tan Tan Ramen and it was perfect for a winter day. The ramen comes in a spicy soup base with pork belly and simple veggies. It's an instant warm-up from the freezing weather. I find their menu kind of small. It must be because they are more specialized... but I would love to have more selection.
Overall I had a great experience - convenient location, good ramen, friendly staff and prompt service. However, I probably won't return anytime soon due to the limited menu. To be honest, it wasn't anything memorable besides standing in the cold while waiting for a table...
