Pretty decent Ramen that is NOT coming from your usual chain/franchise Ramen restaurants. I ordered the hokkaido Ramen and the soup was very flavourful (similar to a tonkotsu Ramen) and the noodles were well done. What was nice was that their Ramen came with more toppings compared to other Ramen joints, but I found their chashu to be a little rough and not nearly as flavourful as kinton's.
They also have other dishes such as the unagi don (which was deliciously made), as well as sushi dishes, too.
Although Koi Sakana is not my favourite Ramen restaurant, it is quite worth it for the price, and they have take out which is perfect for those who work around the area.
