I went to Muroya as part of the gentei adventure; trying a bunch of the crazy seasonal productions that are popping up with the changing of the leaves. Would you pay almost double for a bowl made with some of the most expensive mushrooms in Japan? Mushrooms that spring forth but once a year? You bet!
But they were still sourcing ingredients for their matsutaka mushroom invention, so the normal bowls would have to suffice.
The tsukemen was solid, but missing something. Missing $100 mushrooms perhaps.
Whiffs of yuzu kick up the ramen a bit, though I would rather be whiffing some matsutakas.
Decent shop though, and right next to beautiful Shinjuku Gyoen Park. The fare is your standard pork and fish blend, with some excellent grilled chashu on top.
