AI summary of what 2 dish mentions say about the food
Isen’s tonkatsu earns rave reviews for its impossibly crisp, juicy perfection, creating a warm, comforting vibe that feels like a genuine culinary hug.
“This tonkatsu is cooked first at low temperature and then fried, so the center stays soft and slightly pink — don't be alarmed, it's traditional here. The sauce is already on it. The breading is incredible, so crunchy. The meat is so tender you can cut it with chopsticks. Look at this slice — wow, splendid. The low-temperature cooking makes it soft inside, very luminous. This is the best meal I've had so far in Tokyo. I spent 4900 yen, about 25-30 euros. I ate like a god. If I ever come back to Tokyo, I'd come here with my eyes closed.”

Ebi Furai
The shrimp fry is also excellent — crunchy and perfectly fried. The pumpkin side dish is great too, with lots of spring onions inside. Everything is served with white rice and miso soup. The miso soup here is also delicious.
