After ten years as a vegetarian I'm back on fish, and I'm wondering where's a great place for Mexican seafood. I tried Isla Azul (on the Reader's rec) and thought the salsa was divine, but nearly choked to death on a bone from huachinango a la veracruzana! Particularly of interest would be a taqueria with good, cheap fish tacos. I'm just having fun exploring the options beyond cheese & beans. So much temptation in things like carne guisado and caldo de res, but I'm not quite ready to make that leap yet.
