FNG, a rock-and-roll-themed hit from prolific chef/restaurateur Troy Guard, more than lives up to its name: It’s fuckin’ good. It also manages to be a neighborly place with nothing to prove — except maybe that comfort food from a restaurant can be just as good as homemade. The vibe is youthful and raucous, slightly diner-like on the perimeter, where garage-door windows flood a family-friendly section of booths with fresh air and sunlight. Vintage album covers decorate the walls, many from Guard’s teenage collection. Servers sport band T-shirts, and ’70s and ’80s rock and heavy metal is cranked at all times, sometimes so loudly that you’ll shout or give up trying. The menu straddles the line between nostalgic and contemporary, with a mix of small plates, sandwiches, housemade pasta and down-home favorites like meatloaf and chicken-fried steak. Just have fun trying to explain to the kiddos what the initials FNG mean!
