The IASS Superior Lounge NOA in Narita Airport had one bad review complaining about there only being noodles and bread. Since it was close to my gate for leaving Japan, I went in anyway.
The food is all Japanese. When I went in October, 2023, in the late morning, the food options were a variety of small pre-meal dishes, soba to cook in the spot, onigiri with soy sauce, mochi with red beans, and an pan bread or cream pan bread.
The offerings may look small, but they were frequently checked and replaced. For example, the soba’s cooking water/pot was changed at least 4 times in the hour I was there.
The lounge was comfortable, quiet, and not crowded. A few non-Asians came in briefly and left in disappointment, but all the Asian visitors seemed content with the offerings. I had an excellent pre-flight meal and liked the food, though I think someone looking for varied alcohol or food will be less happy.
I will have to remember not to pair mochi with red bean with orange juice! I was enjoying the mochi/red bean and then found the deliciousness replaced by disgust when I had a sip of my drink!
