Matsuya Nakameguro is on Yamate-dori near Nakameguro Station and serves gyudon and morning set meals. The gyudon comes with a pork soup set, and the double fried egg morning set can also be ordered. It is a self-order shop where customers buy a meal ticket at the entrance kiosk and sit at a U-shaped counter, and food is often called out right after ordering. Oil and food residue are left on tableware and tables, so cleanliness management falls short.
