Tabelog ratingT's Tantan (T's たんたん グランスタ東京) has earned a strong reputation for serving high-quality, entirely vegan ramen from a surprisingly convenient location: inside the ticket gates of Tokyo Station. It specializes in tantanmen, a spicy noodle soup, delivering all the creamy richness and umami of a traditional bowl without any animal products.
Reviewers consistently praise the signature Gold Sesame and Black Sesame tantanmen bowls for their deep, nutty flavours derived from a peanut and sesame broth. The soy-based 'char siu' pork is also frequently complimented for its convincing texture and taste. Other popular items include the vegetable gyoza (ベジ餃子) and the grilled soy 'char siu' (炙りチャーシュー) as a side. The staff are often described as polite and English-friendly, and ordering is done efficiently via a tablet.
The main challenge for visitors is finding the restaurant, as it is located within the station's paid area near the Keiyo Line platforms, and queues are common during peak lunch and dinner hours. Some diners note that the broth is milder than they expected for tantanmen, and a few feel the portions are a little small for the price.
A typical lunch costs under ¥1,000, while dinner is usually between ¥1,000 and ¥1,999. Reviewers recently paid around ¥1,250 for the signature Gold or Black Sesame tantanmen, with a basic bowl starting from ¥1,100. A side of three vegetable gyoza costs about ¥400. Most diners, especially those seeking plant-based options, consider it good value for the quality and satisfying flavours.
