The train goes like a bullet really.
The Japan Rail Pass is worth it only if you make a return trip to Osaka from Tokyo.
Sleek and super fast.
TLR: his second time on the bullet train.
And, finally, I was pleasantly surprised to see attendants wheeling food trolleys - just like in an aircraft except that you have to open your wallet!
Hopefully, if I go to S Korea in autumn I'll be able to tell you whose bullet train experience is better because they have something similar.
