Seosan izakaya sashimi for two with ankimo: Masinneun Seonmul Ato

In short

Masinneun Seonmul Ato (맛있는선물 아토) is an izakaya on Yecheon 7-ro in Seosan, Chungnam. After booking a weekday evening table, the writer ordered the assorted sashimi for two and a whole steamed squid, and the sashimi platter came with a generous heap of rich ankimo (monkfish liver). With fresh sashimi and two big squid, Masinneun Seonmul Ato is a Seosan izakaya worth a return visit.

When you think of an izakaya (Japanese-style pub) in Seosan, which place comes to mind first? The one I visited this time is called "Masinneun Seonmul Ato" (맛있는 선물 아토), and the meal was so satisfying that I just had to introduce it to you!

What is Masinneun Seonmul Ato like on a weekday evening?

I booked ahead and visited Masinneun Seonmul Ato on a weekday evening. While choosing from the menu, the whole steamed squid caught my eye ><

The seating is really cozy, and even though I went early, there were lots of customers. Booking ahead was definitely the right call. Also, Ato is running a Naver receipt review event, so be sure to join in ~

Ato's standard side dishes on the table

Free side dishes at Ato: tangy seasoned bean sprouts

These are the side dishes Ato serves by default. The bean sprout salad was the surprise: the sauce is so refreshing that it's perfect for cleansing your palate. I also tried the well-cooked tomato and it was secretly really good, haha!

Next, the menu at Ato, a Seosan izakaya!! I ordered assorted sashimi for two, plus the whole steamed squid, haha. The drinks list is varied too, so anyone who loves a drink will probably love this Seosan izakaya :)

What comes in Ato's assorted sashimi for two?

An exciting spread arrived! This was the assorted sashimi, and it was really generously put together. You get to taste many kinds of fish, so choosing the assorted plate was the right move :D

Anko served alongside the assorted sashimi

What truly shocked me was the anko (monkfish liver) they just piled on, haha! I really love anko, and they gave it to eat alongside the sashimi. I was so happy!! The sashimi was wonderful because I could eat loads of rich, melt-in-your-mouth anko 🤍

I went with an acquaintance and had a great time at Ato in Seosan. If I get the chance I'll visit again, because it was so good that I'm now curious about all the other dishes too.

I was so moved by how fresh the sashimi tasted. When you're craving raw fish these days, you want somewhere truly trustworthy, right? The fish at Masinneun Seonmul Ato was really fresh and in great condition, so I could eat with peace of mind. It was delicious :) Good good!

Everything in the lineup, from the abalone to the tuna, was delicious 🤍 At this quality, I think the price is good value too.

Private rooms at Ato for dates, groups and work dinners

It's great for eating and hanging out with friends, good for a atmospheric date, and I think it would work for a get-together or company dinner too. I sat in the hall, but there are also room seats at the back, so if you like, reserving a room in advance sounds like a very good idea ><

Every single piece was delicious ^___^ Thinking about it now, I want to go back for another piece of fresh, tasty sashimi, haha. It was great with wasabi, great topped with anko, and great just dipped in soy sauce 🤍

Unusually colored wasabi, plus seaweed and rice

At Ato, this Seosan izakaya, they seem to make their own wasabi, because the color was one I'd never seen, and it was really tasty! They also served seaweed and rice, which was great to eat together (the best combo, haha).

Two huge whole steamed squid

Is Ato's whole steamed squid worth the 15-minute wait?

Next up was the whole steamed squid, which took a bit of waiting. They said the squid is big, so steaming takes about 15 minutes, but I didn't mind, so I ordered it, haha.

The size was seriously big. Plump squid that make you happy just by looking at them~ Two very large squid come out, so I think you could be full from this alone! They pick only squid in good condition, which I was really grateful for :)

Every time I cut the steamed squid, innards came out, and wow.. it was incredible!

I cut the squid into bite-sized pieces and ate it with the innards, and it was so nutty, rich and delicious, T_T the kind you want all to yourself!!! It's so good that I highly recommend it ~!!
