I dont understand why there has to be such a hype when it comes to Japanese food that the food has to be authentic and that the establishment has to be owned by a true Japanese person. Trust me, I'm pretty sure a true japanese person could make a bad bowl of ramen. Koi Sakana is more than capable of proving other establishments that they know how to make their ramen.
This place is quite cozy, standard size but what really stood out to me and my partner was that the quality of the two dishes that we ordered.
The Hokkaido ramen had an incredibly rich and savory broth but the flavour for the curry in the curry katsu did not impress us. However, the size and crispiness of the katsu that came on the side made up for it. I also appreciate how the ramen came with an egg. As sad as it sounds, I do not think it is a good idea for ramen places to continue to charge extra for an egg - it leaves a bad taste in my mouth and I tend to avoid those places (i'm looking at you kinton)......
Overall, I think this is a solid place to go for a bite. I just wish there was a combo with just the katsu and the Hokkaido ramen. Definitely looking forward to coming back someday if I come across this area.
