Definitely my top ramen place in Toronto now
I ordered the Miso Ramen and soft boiled egg and my friend ordered a Black Sesame Tan Tan Ramen.
The Miso soup base got mixed reviews. I loved it but my friend said it is too sweet to his liking. He preferred his Tan Tan Ramen that was more on the savoury side.
The egg was cooked perfectly. I will recommend you to put the egg on top of your ramen (don't drown it) for a while before you eat it if you don't like to eat cold eggs.
Both of our ramen came with thick noodles, if you order the Shoyu ramen I think they comes with thin noodles.
For me, I think just the noodles itself is worth another visit to Ramen Isshin. It had the right chewiness (& doesn't get soggy half-way eating) plus it tasted authentic. I can't tell you how many times I got disappointed by soft ramen
