I hadn't been to this "New World cuisine from Brazil, Venezuela, Mexico and SW US" on Exchange St., on the site formerly occupied by O'Naturalsm, but went there Saturday night on the spur-of-the-moment, trying to get something to eat before a concert. I was pleasantly surprised. The setting is large and comfortable, noise levels well below the usual deafening din of many Portland restaurants. While there's no pretense of high-end food, everything we ate was a careful presentation of interesting flavors. You may want to check out the menu at http://www.sonnysportland.com/index.html
Because we were on the run, we made a meal of aps and salad. Empanada was nicely filled and remarkably light, unlike some fried bombs I've eaten, and we also sampled panko-crusted fried avocao, fried plantains, and a "smashed" beet with goat cheese, along with a large and tasty musroom salad. All the fried dishes have a nice light batter, and no oily overtaste. That was more than enough for two of us, and we got out for $45 plus tip, including two beers from a very extensive list. Wines are fairly priced, and the larger plates all look interesting.
Bottom line: this is a tasty, moderately priced addition to the Old Port scene. I'd be interested to hear what others' experience has been, since I haven't noticed Sonny's mentioned before.
