One of the culinary specialties of the Narita area is freshwater eel (unagi)—indeed, on the short stroll along Naritasan Omotesando, you'll see a number of places offering it. This one, close to Naritsan Shinsho-ji, is known for its chargrilled eel, slathered in a savory soy-based sauce and served over rice. Tradition says the dish is good at fighting fatigue, hence, it's particularly popular during the humid summer months. If you are a truly adventurous eater, try the eel-liver soup or the deep-fried eel bones. Takeout orders are an option.
