I visited "SPICY CURRY Roka" in Hyakunincho, Shinjuku, after being invited by an acquaintance.I arrived around 15:20 and signed in for my desired time.I entered the restaurant at 16:50.The owner, Mr. Saito, was working solo and provided excellent service to many regular customers.I ordered the Roka Plate with vegetable curry. It was delicious, with a perfect balance of spiciness and rich flavor.
