This time, I happened to find a cancellation slot and was able to make a last-minute reservation.

How to Order

Ordering method: Select the course at the time of reservation (additional nigiri can be ordered after the course is finished), drinks can be ordered verbally
Payment method: cash, credit card, PayPay

We have a course system, and you will select your course at the time of reservation.

Drinks are ordered verbally to the staff.

After the course is over, you will be asked if you would like to order more nigiri, so if you have the stomach for it, try ordering more nigiri, although there will be an additional charge.

Oedo

This time, we will introduce the most expensive ``Oedo” I asked for the course.

The course includes an appetizer, 3 types of sashimi, an appetizer, a steamed dish, a grilled dish, a small side dish, 9 pieces of nigiri, an egg, a roll, an owan (soup), and a dessert.

Kanto ITS insured person pays 6,600 yen, accompanying person pays 9,900 yen, and additional charges will apply if drinks and nigiri are added.

For those who don't need to cook and just want to eat nigiri, the lowest price is 2,200 yen for the insured person and 3,300 yen for a companion, so I think it will meet a variety of needs.

Now, let me introduce what I received this time.

1st cup: Bin Beeru (Bottled Beer)

For my first drink, I ordered Bin Beeru (Bottled Beer).

The start time is 17:00, which means some people are still working, so the food tastes even more delicious than usual, with a bit of immorality added to it.

Advance: Shirauo

It has the scent of the ocean and a slightly bitter impression.

It's a nice snack that has a chewy and elastic texture that you can enjoy.

Gari

It is a type with strong acidity and is made with red vinegar.

This is my favorite type as it washes away the aftertaste.

Sashimi 1: Flounder

It has a plump texture and a strong flavor.

Sashimi 2: Red shellfish

You can really feel the melon-like aroma and taste that is unique to red clams.

It is a nice red shellfish with a crunchy texture and a sea-like feel.

Sashimi 3: Bluefin tuna

The skin is seared, and the flavor and aroma overflow from the skin.

2nd cup: Kuzuryu

I ordered Kuzuryu hot sake.

It has a rather sweet impression, and I don't think it goes well with food. .

Steamed food: steamed abalone

It has a chewy texture and a strong flavor when you bite into it.

Small package: Shirako and Shimimi soup

The milt is creamy and goes well with the clam stock.

It's pretty hot, and it warms your body.

I think it's okay to put it out first.

Grilled food: Grilled swordfish with salt

It has a firm feel of fat and a fluffy texture.

Nigiri 1: Que

It's the type where you can really feel the flavor.

The greasiness seems to be a little weak.

Nigiri 2: Sumiika

When you chew on the crunchy texture, the sweetness really comes out.

3rd cup: Hiroki

I ordered this because my wife likes sweet fruity foods.

As expected, you can enjoy premium sake whenever you come.

Nigiri 3: Pickled red meat

You can really feel the flavor of the soup stock, and you can also feel the iron content of the tuna.

Nigiri 4: Ootoro

You can really feel the fat and flavor.

Nigiri 5: Ootoro

The big toro continues, but it's not a mistake.

On this day, there was no medium fatty tuna, but two large fatty tuna in a row, a first for the lineup even among other sushi restaurants.

I felt the flavor of the muscle more in the latter part.

Grip 6: Small skin

It is the golden route of small skin from large fatty tuna.

You can really feel the fat and flavor unique to blue fish.

Nigiri 7: Surf clam

When you bite into the crunchy texture, you can feel the sweetness and the flavor of the ocean.

Nigiri 8: Prawns

You can feel the sweetness and the flavor of shrimp miso.

Small bowl: Sea urchin salmon roe bowl

The salmon roe has a strong soup stock and saltiness, so if you eat it together, it will go well with the salmon roe.

Therefore, I think it's easier to understand the taste if you eat the sea urchin alone first.

Nigiri 9: Conger eel

It has a fluffy texture, no bones in it, and no odor.

Scroll: Tekka

The iron content of the tuna and wasabi are combined with the seaweed's seaweed.

When I was a kid, I thought it was a waste to make tuna into rolls, but now that I'm an adult, I can appreciate how delicious it is.

ball

It has a fluffy texture, yam and shrimp, and a slight sweetness.

Red soup stock

It contains sea cucumber, giving you a strong sense of the sea and miso.

Dessert: matcha

Finish off with matcha ice cream.

It's been a while since I had matcha ice cream. .

Impressions and Rating

The total bill was approximately 18,000 yen for the Oedo course (6,600 yen for one insured person, 9,900 yen for one accompanying person) + Bin Beeru (Bottled Beer) + 2 glasses of sake + my wife's drink.

If both husband and wife are insured, the price will be even cheaper, and although I usually add more, this time I didn't because I didn't have anything to add, so I ended up paying less than 20,000 yen.

There is something called a sushi bubble these days, and prices are rising rapidly at all restaurants.

I always think that if you were to eat the same thing at another restaurant, it would probably cost around 20,000 to 30,000 yen per person.

However, even if the content is good, the taste is important.

I think it's delicious in terms of taste.

The last time it was in February, this time it was June, and this time it was December, but I have the impression that it tastes better in winter.

Since the seasons and times are different, the ingredients available are also different, and even the same ingredients may be in different seasons, so it is difficult to make simple comparisons.

If I can eat and drink this content for 20,000 yen, I'd be more than happy to do so, so I plan to visit again in different seasons and times, and try to experience the same time every few years.

I would like to visit again if I can make a reservation.

Overall: ★★★★★★★★★☆ (9)
Taste: ★★★★★★★★☆☆ (8)
Cost performance: ★★★★★★★★★★ (10)
Would Revisit: ★★★★★★★★★☆ (9)
