Seiko Japanese, located in Pak Nam Pran, Prachuap Khiri Khan, is a quaint little Japanese restaurant with about 4-5 tables. The decor is simple yet charming. The menu features a variety of items including sushi, sashimi, drinks, ramen, salads, and snacks. During my visit, I ordered the yakisoba for 79 baht, a seaweed salad for 39 baht, and three pieces of sushi. The flavors of the dishes were delightful and satisfying.
