T's Tan Tan is a lifesaver when you've just arrived in Tokyo, tired, confused & hungry! It's located inside Tokyo Central train station, in a shopping/food arcade called Keiyo Street, so it's easy to find before you get acclimated and get your bearings. You do have to buy a platform ticket (140 yen) if you don't have a train ticket or rail pass, but as the food itself is inexpensive, it doesn't matter much. T's is a vegan ramen restaurant, with about about 6 different ramen options plus 2 curry plates. You can also get a dinner set, where you chose a ramen and small side bowl of rice with curry or soy meat. But I have to say, despite the small menu, I never get tired of eating here (once a week now!) The service is super-fast, the price is right (about 1200 yen for ramen and side), and the food is always delicious. I've tried everything on the menu, but my favourite is the miso ramen with a side dish of soy meat. Yummy, never disappoints!
