The line outside Rokurinsha in the new Solamachi mall can be as much as an hour long. The chances are you'll be ready for a beer when you get to the end of it. Something like a nice big flagon of Sky Tree lager.
It's not actually frozen beer, but the joki flagon came straight out of a refrigerator all lovely and frosted.
Perfect for while you wait (another 5-10 minutes) for your tsukemen to be served. That's a saucer of menma bamboo shoots on the side as the otoshi nibble to go with it.
Trivia: as everyone in Tokyo knows, 634 refers to the height of the new tower.
NB: If that long queue seems offputting, I was told the wait is as little as 20 minutes if you go at the quietest time of the afternoon (around 4 pm) weekdays. Though this may not be true once the summer holidays kick in.
