I ordered the tonkotsu shio ramen in chicken broth. Nothing extra added to first get their basic ramen experience.
Soup base was very clean and light flavoured in terms or saltiness, which I love. Toppings included a soft boiled egg that was made in soya sauce (a touch of authenticity since most places don't have their eggs made in soya sauce). A little bit of green. Literally two of them. Lots of green onion which is a personal favourite of mine for ramen because it complements perfectly for lighter broths, adding that extra freshness kick to the broth. Last but not least, the pork was soft and I didn't have to worry about any of it getting stuck in my teeth. Definitely better than Kinton's pork!
Now, the noodles were of medium texture. That is to say, it wasn't soggy yet not chewy.
I would have rated their chicken broth ramen 5/5 if it weren't for my personal preference of more greens (only two leafs didn't fully satisfy me). I will be back to try their add-ons.
Now to atmosphere and decor, I love how spacious it is and my friend kept pointing out the staff's higher than other ramen shops' class. As in, Raijin has a higher class Japanese service than all the other ramen places, Momofuku included! This is all up to preference of which kind of atmosphere you would like. I think this is what will distinguish them the most apart from their fresher, lighter noodle broths.
Decor was simple and could have used a little bit more thought. I guess the decor is too simple giving a more bland flavour to the place and harder to notice the more sophisticated service they are trying to aim for.
I will be back for sure though. Maybe I can even hope they will open another one closer to the great restaurant area of Spadina and Bloor!
