Every time I go to Toronto, I eat here at least twice. Luckily for me, I'm normally traveling for work solo, so I don't have to wait as long for a table as people in a group. Sometimes the line can be quite intense but I assure you it is worth the wait!
The restaurant itself is a typical ramen shop layout, long and thin with communal tables and a few separated out. The food comes out quick and is absolutely delicious.
If you go, you must order the black tonkotsu! The staff claim its best with thin noodles but I'm a big fan of the thicker style.
