T’s Tantan GRANSTA Tokyo: vegan ramen outside the JR gates

A practical guide to T’s Tantan GRANSTA Tokyo: the operator-listed location, dietary evidence and the details to confirm before you go.

Find the right branch

The current T’s operator page places the GRANSTA Tokyo restaurant on B1F, outside the JR ticket gates. That detail can differ from old station guides. Use the current branch listing and station signs before passing through a gate. For a timed departure, leave room for finding the restaurant and returning to the correct platform.

Officially listed address: 東京都千代田区丸の内1-9-1 東京駅グランスタ東京B1F

What the food information supports

T’s describes its food as vegan, excluding meat, fish, dairy and eggs. The relevant evidence is the operator’s own restaurant page. Individual dishes, availability and service arrangements can differ between locations. Vegan food is not automatic verification of halal seasonings, certification or the presence of a prayer space; ask separately if those details matter.

Before making it your only meal plan

Confirm the intended dish, current opening time and any extra requirements directly. Keep a backup if a particular menu is essential to your day. The advice here does not establish live availability or a reservation.
