Ichino Ya is a freshwater eel restaurant in Shinsen, Shibuya, Tokyo, serving unadon and other eel dishes. The unadon has soft flesh and light seasoning, and shirayaki and kimo-yaki can be ordered as well. It is a branch of an eel restaurant that has run for about 200 years in Kawagoe, and the counter, tables, and private rooms all use horigotatsu seating. Ordering without a reservation means a wait of about 50 minutes to an hour from cooking to table.
