Kishimen noodles at Nagoya Eki Kishimen Sumiyoshi (名古屋駅きしめん住よし), Tokyo-bound Shinkansen Platform, around car 14.

A Nagoya classic and a favorite for those heading from west-of-Kansai transferring to a Kodama for “local” service (I know, a local train running at 175+ mph sounds ridiculous), Kishimen is a variation on Udon in that the noodles are chewy and wavy instead of the usual thin-square cut of Sanuki style, served on a sweet-ish dashi broth. The two bowls here are Squid Tempura and autumn mushroom kishimen. The place is a Tachigui 立ち喰い or standing restaurant where you order using the vending ticketing machine outside then gesture to the restaurant worker how many are in your party – when a spot opens up you are waved in, you give the worker the ticket, and you were served within a minute or so. There are 2 of these on the Up (Tokyo-bound) platform, one in front near Car 14 and one at the back towards Car 4. I think the Down (Hakata-bound) platform also has similar arrangement. For some reason the booth on car 4 is significantly busier than the one on 14.
