Despite all the raving reviews I'm probably in the minority with my opinion, but hear me out. I tried the third expensive variety, dry ramen with A5 Hida beef for 2400y. The service was excellent, efficient and friendly. You order with a ticket machine and there is are japanese and English descriptions. The bowl was served and it looked amazing. Thick chewy noodles with the right bite, a creamy coating when you mix it with the poached egg and a slightly spicy, peppery flavor. But the beef, - despite being tender and cooked just right - had a weird, sour taste. I'm aware that there can be various reasons for that, for example wet aging or acidic soil with grass fed cows, but for beef in that price range I expect everything , nutty, fatty, buttery, etc. but no sour taste. Maybe just bad luck, maybe that's normal for this kind of beef, I don't know. But that's the reason for the low rating. Really nice place but the beef is definitely not worth the money I'm afraid.
