Katsudon-ya Zuicho is a small, no-frills spot where you can expect a fast, very filling bowl of pork cutlet over rice — the signature katsudon is the safe pick and often comes with miso soup and pickles. Seating is likely counter-style or a few tiny tables, so go slightly off-peak if you want to linger; everything is cooked to order so there may be a short wait. Bring cash because smaller places sometimes do not take cards, tipping is not done in Japan, and takeaway is usually available if you prefer to eat elsewhere. Menus may have limited English, so point at pictures or use a translation app to order.
