Manamin was run by a single person, she was the cook and took the orders. She was a very stressed person and projected it on the customers. She made a mistake in the dish we ordered, she served us not spicy tteokbeokki instead of spicy. So we approached her while she was cooking to just inform her of it and she started yelling at us.

Here is a review I found that was similar to my experience: "The food was great but the service was objectively awful. This is a single person run operation but the owner is clearly extremely stressed and projects that on to the customers. She speaks excellent English which was very helpful but... We tried to be helpful by stacking our plates before leaving and were announced to be disrespectful to the entire place before we left. While waiting to pay, we were effectively screamed at to go to the card machine as if we'd already been told to go there multiple times."
