Hard-to-find ramen restaurant

This is dried horse mackerel, salt flavored ramen from Ramen Ajiruku in Otsuka.
The ramen is beautifully presented and tastes outstanding, but the restaurant is very hard to find.
I walked past the restaurant so many times because it looked nothing like a ramen shop!
It's only open during the day as it becomes a tavern at night.
The restaurant is spacious and clean. I highly recommend!
