Tokyo is saturated with thick, porky, Rokurinsha-style tsukemen. Though I love the stuff, it gets a little tiring trying to find subtle differences in a tonkotsu-gyokai soup.
Enter Marucho. An instant top 5.
The soup, though thinner than the other styles, is full of meat and onion bits. So much so that every bit of noodles includes a fair share of umami chunks.
And the soup-owari. Refreshing, with a kick of spicy and vinegary.
As expected, a lunch only spot. The only one of the four branches to be open later is way out at Tskuba University, an hour or so away by express train.
