An American izakaya has joined the growing roster of eateries in Sylvan Supply (Radish Kitchen, Black Dynasty Ramen, and Red Perch are good company). Punk Wok’s Nashville roots stem from restaurateur Clay Greenberg of Germantown’s now-closed Silo, whose bold new concept is bringing a mix of flavors to the table. That means sushi, crab rangoon with pimento cheese, Japanese potato salad with Kewpie mayo, and kimchi fried rice are all available. There’s no lack of personality here, either: order any maki Russian roulette-style to share with friends, in which one piece of sushi has a piece of habanero pepper inside. Whoever gets the pepper takes a shot as a prize.
