Have tried the different ramen joints, including (in my order of preference) Raijin, Ryu, Sansotei, Kinton. I'd think for the signature clam broth ramen, I'll put this right between Ryu and Sansotei. The broth flavour is quite unique and not too salty (finally not overly salty) and the noodles are well textured (slightly flat, not fully round).
The price isn't the greatest.. my bowl cost $14 and didn't include an egg - so the extra egg cost $1.50. Serving size was appropriate, much better than those miniature Sansotei bowls where I'd want an extra order of noodles.
For the tonkotsu one that my mother had (the OG one), I didn't quite like the pickled vegetables within the broth so I took the stars off.
