Irorian Kiraku is a soba restaurant on the basement first floor outside the Marunouchi north exit of Tokyo Station, a four-minute walk from Tokyo Metro Marunouchi Line Tokyo Station. Customers choose soba or udon from a ticket vending machine, then hand the ticket to staff and say their order, which is called out by an automated voice. The restaurant also serves kakiage dishes and a soba katsudon set, and there are seats to sit at. Because of the name Gransta Marunouchi, the location is hard to find from the underground passage.
