Seiko Japanese, located in Pak Nam Pran, Prachuap Khiri Khan, is a small Japanese restaurant with about 4-5 tables for seating. The décor is simple yet charming. The menu features sushi, sashimi, beverages, ramen, salads, and snacks. I ordered the yakisoba for 79 baht, a seaweed salad for 39 baht, and three pieces of sushi. The food was delicious!
