In the stylish basement-restaurant floor of Tōkyū Plaza Ginza, this standard-looking ramen stall has the usual vending machine for paying at the entrance. The key difference is that the noodles here are topped with slices of the potentially dangerous (but here completely safe) fugu (pufferfish). It's a bit of a novelty, but one worth trying.
Do order a side of fugu karage: the fish tastes far better deep-fried, but watch out for bones as you munch through it.
