Chef Eric Donnelly built his casual raw-beamed fish house as a Montana fishing lodge smack in the heart of upper Fremont. And if the deep menu seems overambitious—a dozen each of small plates and large ones, and that’s just the seafood—Donnelly has navigated his share of long menus in corporate restaurants, with startling success. Here, his wild Mexican prawns over Anson Mills grits is a sure-handed and bright Napa Valley–style plate; his mad variety of finfish preparations, often topped with handfuls of leafy herbs, are exact and supremely satisfying. Affable service completes the picture; a perfect place to bring your out-of-town guests. Open late.
