Kenzo is ass, how can you not mention Santouka? Santouka and Sansotei are easily the 2 best.
Santouka is terribly boring. Bland decor, bland ramen, even the cooks seem bored. Nobody in that place seems to be happy like every other spot I've been to. Kinton cooks and service staff are the best example of being fucking psyched to serve you delicious ramen.
Nothing about it is remarkable, in my opinion.
