The homemade udon noodles served at Sawanoi make for a perfect light meal or a midnight snack. The menu, available in English, lists a range of noodle dishes, hot and cold, served in combination with seafood, vegetables, or meat. Try the inaka (country-style) udon, which has bonito, seaweed flakes, radish shavings, and a raw egg dropped in to cook in the hot broth. For a heartier meal, chose the tenkama set, which consists of hot udon and tempura that you dip in a delicate soy-based sauce.
