Southern Chile is a good place to eat good fish. The small port town of Chaitén has just a handful of basic restaurants all serving the same things: chicken, pork or fish. The fish seems to change somewhat from day to day, with salmon and hake being vaguely consonant.
Today we tried two white fish, one of which we think was swordfish and the other is unknown, but both very tasty with generous and freshly prepared side dishes of rice, salad and potatoes. The fish is very simply cooked, but then such fresh fish really doesn't need a lot of messing with to taste good, and we appreciated that a lot.
