Overall, Katsuya is described as a go-to spot with huge portions, crispy katsu, and a wide mix of sauces and variations including curry, rose, cheese and takoyaki, commonly paired with udon or rice and a friendly, efficient vibe during lunch. While many reviews praise texture, generosity and authenticity, some dishes are noted as average or oil-heavy and service can be slow or understaffed at times, detracting slightly from the experience. The downtown location and reasonable prices are seen as positives, though a few comments mention waits, crowded spaces and occasional inconsistencies across visits.View restaurant profile
