Where To Find Fish Tacos?

Taqueria Nacional fish taco

A Metrocurean reader writes in search of the best fish tacos in town. DC being a long way from Baja, it seems the options are a little limited. But perhaps you can prove me wrong in the comments.

I like Taqueria Nacional, whose fish taco is pictured above. Ceiba serves a Baja-style version at lunch and on its bar menu. Where else can you find good fish tacos?
