Unagi Sanya is one of those under-the-radar places that’s been around longer than the hype cycle. Fifteen years, to be exact. They only use large, fresh-cut eel, not the pre-marinated stuff, and the difference is obvious the moment your bowl hits the table. The eel is steamed before grilling, which helps reduce oiliness and makes the bones soft enough that you don’t even notice them.
The sauce has been simmered and refined for over 15 years, thick and not overly sweet. They also serve solid sashimi, which is a rare bonus for an eel spot. It’s the kind of place you’ll quietly recommend to friends.
