01 / ABOUT THE PLACE

About this place

Made entirely without meat, seafood, or other animal ingredients, the noodle bowls at T’s Tantan have built a devoted following for their depth of flavor. The flagship Golden Sesame Tantanmen features a smooth, creamy broth infused with roasted sesame that clings tightly to the noodles, offering satisfying heartiness rarely expected from plant-based cooking. Those wanting deeper roasted notes can opt for the Black Sesame Tantanmen, while anyone in the mood for something lighter can choose the Yuzu Vegetable Shio Ramen, accented with bright citrus.

Beyond noodles, the expansive lineup of side dishes and rice bowls adds practical versatility. Well-regarded vege gyoza, savory seared vege chashu, and soy-meat sides make substantial accompaniments when dining with a larger appetite. With options extending to rice bowls like the Vege T's Curry & Buddha Bowl or the Tantan Bowl, as well as oat-milk iced matcha lattes and craft beers, the cafe caters just as easily to diners not craving ramen.

The shop is situated on basement level 1 of Gransta Tokyo, in the Square Zero area outside the ticket gates, so JR train tickets are not required to enter. Its casual dining room includes counter seating, and digital ordering paired with quick payment makes it well suited for a solo meal between journeys. In addition to dine-in service, bento boxes, vegan instant cup noodles, and baked snacks are available to take away, making a convenient option for meals on the go.
