AM STRAM GRAM nobolyquedaly Gransta Tokyo is a tart and cake shop in the basement inside the JR conventional line gates of Tokyo Station in Chiyoda City. Its fruit tarts are topped with fruit and a reduced-sweetness custard, and the tart crust is baked crisp. From 9:30 to around 11 a.m. only a few kinds are displayed, and more items come out around noon. The prices are on the high side for the small size.
