My company usually puts me up in the Toyoko Inn, one of Japans premier business hotels. Business hotels are generally a no-frills deal; room, TV, shower. I actually recommend Toyoko Inn. There are branches all over the country, usually next to the station, and you always know what you are going to get. I've stayed at some off-brand business hotels that were less than ideal.
So when a friend recommended a ramen shop by the same name as my hotel, a few minutes walk from my hotel, I had to go.
Toyoko is super old school.
Greasy, worn out menus were unnecessary, as the standard miso with extra vegetables is the way to go.
Known for overly salty broth, Toyoko serves their noodles with a side of clear, hot broth. Dilute it as much as you want, but I recommend slurping those noodles as is.
The super strong taste is popular with, for some reason, a bunch of older Japanese rock bands. Sorry, I'm no expert on the sounds of Akanofuru and Heroine, Champagne, or Big Mama.
Sorry about that.
