Shibuya Matsukawa - main branch is an eel restaurant in Shibuya, Tokyo, serving unadon, freshwater eel over rice. Diners choose between 130g, 170g, and 200g portions of eel, cooked to be moist and tender. The shop is small and sits in front of a main street, which makes it hard to find, and the interior is quieter than the street outside. Unadon here costs more than other dishes.
