I've been a regular here for years now. Best ramen outside of Ramen Street in Tokyo Station in my opinion. Proper ramen is my favorite, because I can't cook it myself.
Punch your details into the tablet out front and wait to be called. No bookings here. So peak busy times can have you waiting a while, but it's worth it.
Post Covid, you scan the QR code on the table and order on the website, although in typical Japanese fashion, the food comes out fast.
The spicy tonkotsu is my favorite (although friends have melted from tying mine). The pineapple flavored beer is amazing (don't knock it until you've tried it) and so are the pork gyoza. There is also a free half or full noodle refill per bowl. So don't eat all the good stuff straight away, save it for more noodles later. They really don't want you to leave hungry and I really love that about this place.
