Marugame in the Kagawa prefecture not only has one of the 12 original Japanese castles left but is also famous for its Udon. Udon noddles are made out of wheat like most ramen noodles, but are thicker, springy and get served with a very light broth. Usually one does not add a lot of toppings as the noodle by themselves do the job of filling you up while being really easy on the stomach.
Now here is this place in the middle of nowhere with a staggering Tabelog rating of 4.02(!) which can only be described as a shed. (There is one other place close with a slightly higher rating (4.04) which is so remote that neither Google nor Apple give you options to get there using public transportation).
Udon gets served in a self-service style. One first decides on the amount of noodles which get prepared freshly for you. Then you wander over to the counter where you add the broth to your noodles. Lastly you pick the toppings, maybe some tempura or just chives and an onsen egg. Then you find yourself a seat either outside or inside (does not make much difference as there is shade outside and no AC inside). Once seated you start slurping and instantaneously forget about any trouble you might have in your “normal” life. The soothing smoothness of the udon noodles, paired with the broth and an onsen egg will wipe your mind, give you pleasure and peace.
Only in Japan where you can easily spend €500 for a high-end meal you get fed deliciously for less €5 (¥550), this is no typo. You go home and start believing again.
