They are famous for their chicken soup base ramen. Indeed, it is really the authentic and thick chicken soup. I had drank the same type of soup base in Vietnam where they only used chicken bones and meat to make the broth, the real chicken soup. But not as thick as Marutama's one. In fact, I prefer the one I have tasted in Vietnam which is less thick. But still, this is one Ramen which you can't miss.
Not like normal Japanese ramen restaurants like Ajisen Ramen etc, their choices are quite limited. But it appears as a good thing to me, no need to scratch your head to think what to eat.
Their ramen ordering goes like this: You order a basic ramen with only the ramen, soup base and spring onion and seaweed, starting from $12. And then you can add on type of toppings you want, eg: char sew, egg, seaweed etc. Some recommendation for the toppings, choose this special half boiled egg, which you have this hard boiled white egg but half boiled york, sound amazing right? Just wonder how they make sure every egg is like that. And their seaweed is really nice and chewy.
For their side dishes, I would recommend their grilled roasted pork (char siu). The tender in and just nice grilled roasted pork. I would say this is the best I have tried so far. Some other good side dishes like omelet and dumpling worth a try too.
Overall, it is one good choice if you crave for ramen. Although they always have a long queue outside and quite a small restaurant but their service is fast. Turnover rate should be quite fast too.
