The eel, carefully deboned and steamed before being grilled over binchotan charcoal, has a melt-in-your-mouth texture that is simply the best!I arrived around 10:20 AM on a weekday and was the first in line. If you come later, the turnover slows down, and the wait can be quite long. I recommend arriving early, even if you're alone, as you can reserve a spot. However, it seems you cannot enter unless your party is complete, so please be aware of that.By around 10:40 AM, people started lining up, and there was quite a queue by the time the restaurant opened.You place your order verbally from the menu, and payment is settled afterward.The menu features only the new eel donburi. You can choose to add either liver soup or clear soup, but there is also a limited quantity set called the new eel gozen, which includes grilled liver.If you want to try the grilled liver, this is the only option (there were only four sets available that day).New Eel Gozen: JPY 6,900The interior has various seating options, including tatami mats, tables, and a counter, but it is not very spacious. Strollers and large bags will likely need to be left in the space in front of the restaurant. Please note that they mention they cannot accommodate children who cannot sit in a chair.
