Went to Brazilian restaurant in Orleans that opened last spring. Probably the best meal I've had on the Cape. Didn't try the American/fried seafood, but the moqueca and seafood in coconut sauce were excellent. The flan was good as well.
They're open for dinner in the off season, and have a bakery as well. It's BYOB, although they're working on a liquor license. Beer is available across the street at a supermarket.
Definitely worth a try.
