In Asakusa, there is a cozy family-run restaurant where you can enjoy sushi and eel. The atmosphere is so welcoming that you end up staying longer than planned, with drinks flowing freely. We started with a light snack of fruit tomatoes with salt. Despite the restaurant being busy with 40 orders of grilled eel bento boxes, the friendly hostess still took the time to laugh at our silly jokes. The grilled eel liver takes about 20 minutes to cook, so we ordered homemade sweet potato tempura while we waited. Let me tell you, this sweet potato tempura was beyond amazing - the best I've ever had in my life! I'm not usually a fan of tempura, but this one was exceptional. We were even tempted to take some home, but they warned us that it wouldn't taste as good once reheated. So, we decided to come back for more while it's still fresh. Just as we were savoring the tempura, the grilled eel liver arrived, with its fresh and tender texture and perfect bitterness. Of course, the star of the show, the eel, was delicious - the steamed one was fluffy and went well with sake, while the grilled one was crispy on the outside and tender inside, making it a refreshing snack with wasabi. As a finale, we ordered a small portion of eel since we had indulged in too many snacks and drinks. The carefully grilled eel, with its lightly sweet and refreshing sauce, paired perfectly with the firm rice. Surprisingly, we polished it off quickly. The eel was thick and fluffy, and the rice was just right - everything was satisfying. The kindness and thoughtfulness of the staff made our only day off a truly wonderful and happy time. We had such a great time that we will definitely be back again.

The eel restaurant I decided on instinct for the first meal of the New Year turned out to be quite satisfying. Even during the New Year, there was no shortage of dining options in Asakusa, as most places were open. While exploring, my companions and I decided on this restaurant based on our instincts. The kanji characters on the sign of the eel restaurant "Asakusa Unagi Oonaga" were difficult to read due to their stylized form, and this was my first visit without any prior research. The place was bustling with customers, and we ordered squid simmered in soy sauce, red Kirishima shochu on the rocks, red Kirishima shochu with soda, grilled clams, and two servings of eel rice bowls. The eel was cooked well with a good balance of flavors, tender and delicious. The sauce was not too sweet or salty, but light and flavorful. While we did not opt for extra rice, the normal serving was quite small, so I recommend getting the large serving for a more satisfying meal. Overall, the eel rice bowl was delicious and left us wanting to come back again. As we relaxed after the meal, the aroma of a neighboring table's hot pot was tantalizing, and even though we didn't order it, the reactions of those who did made us believe it was also incredibly tasty. As of January 2023, the restaurant has a rating of 3.09 on Tabelog.

I love eel, so if asked what I want to eat, I would answer eel. There are many eel restaurants in Asakusa. I was taken to a few places, but I really liked Oonaga-san. It was very delicious... The staff were friendly, and they had a good selection of sake and shochu. The grilled eel liver was big and satisfying, it was delicious! I want to go back to this restaurant again. Thank you for the meal~ I wrote a blog about it.

A hidden gem of a restaurant a little off the beaten path. Although it took a bit of time, the prices were reasonable, so I wasn't expecting much, but the portion size was generous and the food was delicious. It's hard to find this quality at this price in Tokyo. I will definitely come back.

The two-tiered eel rice bowl was a good deal, with 0.75 eels for 2450 yen and 1.5 eels for 3850 yen. I decided to order the two-tiered eel rice bowl without hesitation. I added extra rice and liver for 4250 yen. While waiting for the meal, I looked at the appetizers and saw a variety of sashimi and side dishes, as well as a sushi menu. It seems like this is an eel sushi restaurant. As for the crucial eel taste, it was steamed well and grilled just right, but the eel itself was a bit too fatty, making it too soft and lacking in texture. It seems impossible to get the best eel rice bowl at this price. Nevertheless, I left feeling satisfied!

I really liked the eel here, so I went to a famous restaurant in Honjo Azumabashi to try it, but it was closed because it had already sold out. It had only been open for about an hour. So, I took the train to Oonaga-san. It was the day of the Sumida River fireworks festival, so the restaurant was bustling. My friend was very happy with my choice. It's a reasonably priced and delicious restaurant that I really like. It seems to be a family-run business with many regular customers. There are many eel restaurants in Asakusa, so I would like to visit different ones if I have the chance. Thank you for the meal!

I entered the restaurant on the way back from Sanno Tori. Inside the restaurant, there is a sushi counter on the right side, and the rest of the area is set up with table seats and raised tatami seating, giving off a nostalgic traditional Japanese restaurant vibe. The menu is extensive, with seasonal dishes listed on a board as well. We ordered various dishes such as grilled chicken liver and ginkgo nuts, and they were decent in terms of presentation, portion size, and taste, making us excited for more. Later, we ordered grilled white eel, an eel rice bowl (Matsu), and a medium fatty tuna roll. The prices for the eel dishes were reasonable given the current market situation, but the small portion sizes were a bit disappointing for modern eaters. The pricing for the eel rice bowl and grilled eel being the same was a bit puzzling. The medium fatty tuna roll was priced on the higher side, but unfortunately, it had a slight off smell. The service from what seemed to be the daughter of the owner was very good, and the one-dish items were decent, so it was a shame that the overall experience left a bad taste in the mouth.

It's delicious. Simple. It may lack a bit of thickness in the meat, but it's delicious.

On weekends, Asakusa is crowded with people, and restaurants are all crowded. Around 4:30 pm on a weekend evening, I walked around looking for a less crowded restaurant. This place couldn't be seen inside from the outside. When I opened the sliding door, there were only 2 customers. We had appetizers for 200 yen, a medium-sized draft beer for 650 yen, and a highball for 550 yen. The grilled eel was 2,850 yen for 1.25 pieces, which means 0.25 pieces cost 516 yen. Personally, I consider 0.25 pieces to be around 650 yen, so it felt like a good deal. The taste was not bad, but there was a piece of plastic wrap stuck to the eel, which made me wonder if it was frozen eel.

The title says it all (lol) Asakusa has many eel restaurants, so I was wandering around looking for a delicious eel place. I stumbled upon this shop. It's ranked 20th in the "Asakusa Unagi" ranking on Tabelog, which is a bit mediocre (lol). Popular eel restaurants tend to be crowded, so even if a place is delicious, those ranked lower tend to be overlooked. And then there's "Dainaga." For someone like me who wants to eat good quality eel at a reasonable price, this was a great find. The eel, carefully grilled after ordering, had a crispy surface with a fragrant sauce, tender and juicy meat, and rice soaked in the sauce. Delicious! It also comes with miso soup and is priced in the 2,000 yen range, which is reasonable. As for other menu items, besides sushi, it's mostly izakaya-style dishes. I noticed that the counter seats have glass panels like a sushi restaurant. After enjoying the eel, I ordered the shop's recommended "tamagoyaki." It was thick, flavorful, and delicious! I really liked it. I also tried the tuna sashimi, which was surprisingly not fishy at all and very tasty. I think I found a great restaurant. The only downside is that the prices for non-eel dishes are high, including the drinks like sake. Despite the delicious food, this might be why there are few customers. The shop is not facing a busy street, so that could also be a factor. Even during dinner time, there were only a few customers (sweat). Overall, I didn't try all the dishes, but everything I had was delicious. If you don't mind spending a bit more for good food, then I highly recommend coming here for the reasonably priced eel dish. It's always empty, so it's perfect for those who want to enjoy a delicious meal without worrying too much about the cost. Just don't have overly high expectations for the taste (lol).

Asakusa - Sensoji Temple Street, turn at the corner of "Owariya Honten" and enter Koen Street. At the first crossroads, you will find "Sushi Unagi Oonaga." I have passed by several times before, but this is my first time visiting. Inside the restaurant, there are 5 counter seats, 3 four-person table seats, and 2 four-person sunken kotatsu seats. As it is my first visit, I ask to see the menu. On the whiteboard are the recommended dishes "Unaju - Matsui" for 2,850 yen (excluding tax) and "Unaju - Ume" for 2,450 yen (excluding tax). When I inquire about the difference, I am told that Matsui comes with one whole eel, while Ume comes with 3/4 of an eel. I decide to order the "Unaju - Matsui." A short-haired, white-haired, slender middle-aged man named Katsuyuki Nagashima, the second generation of Oonaga, says, "It will take about 30 minutes, is that okay?" Of course, I agree. He exudes a charming Edo artisan vibe. Oonaga, after 70 years since its founding, is now run by the second-generation owner, his wife, and daughter. As I watch other customers receive their "sashimi platter" and "tempura," everything looks delicious. Just as 30 minutes pass, the "Unaju" arrives. The daughter says, "Customers say the eel is small." No, this size is the standard for Edomae eel. The exterior is crispy and fragrant, while the steamed flesh inside is creamy. The sauce is a sharp blend of soy sauce and mirin. The daughter humbly mentions, "In Asakusa, you can't call yourself a long-established store until 100 years have passed." The taste of the eel indeed exudes the dignity of a long-established store. Thank you for the meal!

After visiting Senso-ji Temple, we decided to have some eel, and stumbled upon this restaurant. Despite being intrigued by the menu display, we entered and ordered the 1900 yen eel rice bowl. Suddenly, the owner seemed to be handling everything alone and things got chaotic. We waited for over 40 minutes. Finally, the eel rice bowl arrived... The eel was soft overall but the meat was thin and it felt like we didn't eat much. It was a disappointing experience. After a few more customers arrived and seemed to be in the same situation, I told myself that I wouldn't come back and left.
