Osugi

Welcoming lunchtime diners on the 3th floor of an East Gotanda building—in a space that doubles as an evening lounge—Osugi makes broth-driven tsukemen and richly flavoured abura soba its daytime focus. Amid a relaxed setting of booth seats and counter stools, the kitchen serves deeply crafted noodle dishes.

Pairing Soy Sauce or Salt with Bonito or Dried Sardines

The defining appeal of the tsukemen lies in the ordering system, which allows guests to tailor the sauce base and soup stock to their liking. Diners choose between shoyu (soy sauce) or shio (salt) for the tare, paired with either katsuo (bonito) or niboshi (dried sardine) broth. This allows for classic combinations such as shoyu with katsuo for deep, rounded umami, or shoyu with niboshi for a bolder seafood accent. Chewy, thick noodles grip the concentrated dipping broth thoroughly, and additions like menma bamboo shoots or seasoned soft-boiled eggs turn the bowl into a substantial meal.

Ocean Aromas and Finishing Soups for Abura Soba

The restaurant's other fixture, abura soba (brothless noodles), comes generously topped with bonito flakes and nori seaweed, greeting diners with sea aromas. After mixing the bowl thoroughly to coat the noodles in tare, an enjoyable way to finish is adding the separately ordered wari-soup (dilution broth). Pouring in this rich seafood broth shifts the dish toward a tsukemen style, while splashes of vinegar or chilli oil adjust the profile further, keeping the bowl engaging right down to the final drop.

Service runs exclusively during weekday lunch hours from 11:30 to 14:00, and payment is cash only. It is an easy pick for a solo midday meal between work commitments, as well as a relaxed lunch accompanied by a small bottle of beer or a highball.
