Mmm, delicious. The gyuutan was pretty good, but I let him have all the intestines.
My JR pass' official last gasp was a one-hopper from Ueno-eki to Uguisudani-eki on the Yamanote line. Forget rush hour, the last trains on a Friday night are pretty darned crowded, too (not so bad for one stop, though).
And now... To bed, perchance to dream. Or something like that.
