Located in the basement of the Otemachi Building right next to Otemachi Station, Little Koiwai is an established stir-fried spaghetti eatery often cited as an origin of the Rome-spa culture. The most popular dish is Japone, featuring pork, onions, bell peppers, and mushrooms stir-fried with garlic soy sauce; the fragrant soy sauce aroma blends with the tender, thick noodles, keeping diners eating even when full. Classic options also include Napolitan with nostalgic sweet ketchup, Japanese-style soy sauce basilico, and spicy keema curry spaghetti; regulars typically customize their plates as they eat using tabletop grated cheese and Tabasco. The interior has just 14 seats and recalls a mid-Showa coffee shop, where table-sharing is normal at lunch. Staff take orders while guests are in line, allowing dishes to be served shortly after sitting down, and some visitors also stop by in the morning for sandwich Takeout.
