I eat broth-based noodle dishes often. Maybe once every two or three days (I even review them on Instagram). I have to agree with sentiment - some of my favorite dishes, besides tonkotsu ramen:
Lhaksa - curry-based broth with thicker round noodles. Usually pretty spicy!
Pho Ga - chicken-broth based pho; nice departure from beef pho, and seriously delicious.
Khao Soi - a Thai dish; from what I've had of it, seems like a lighter Thai curry broth with noodles similar to lhaksa. Delicious! Had it my first time the other day.
