Marumen in Fairfax is known mostly as a ramen shop, but they have a few other popular Japanese dishes that don't show up on their online menu, like donburi and fried rice. They also have a nice list of specials.
My first impression is that this is a good address to know. I tried two items: the ultraman tsukemen, which is a miso-based ramen, but the noodles are served separately for dipping. Nice flavor, but I expected the dipping 'sauce' to be thick, so I am not sure this really works as an alternative to ramen. The pork was very good, and so was the marinated egg.
Better, though, was the vegetarian ramen, which was full-flavored and a bit peppery. Excellent stock. Served with breaded and fried shiitake mushrooms which were not easy to eat. They would be easier to eat with a knife and fork.
The noodles in both cases were served at a good firmness. I am definitely encouraged to return.
