Gangnam eel restaurant for three-way hitsumabushi: Unagiwa
Unagiwa is an eel rice bowl restaurant near Yeoksam Station in Gangnam, Seoul, serving hitsumabushi in several ways. I ate it plain, with toppings, and as ochazuke; the sauce was nicely restrained rather than overly intense. Verdict: a great pick for a neat, satisfying eel rice bowl meal.
