I poked my head into Xaga, a diminutive but attractive sushi and Asian fusion place done in bright neons and shiny black surfaces. The friendly host was glad to hand me a menu, which revealed such Asian fusion dishes as crispy ginger duck and Thai curry chicken. On the roster of maki creations were a “passion roll” made with yellowtail, cucumber and avocado and a “Northport roll” made with eel, king crab, avocado, mango and mango salad. Wait a minute, Northport? Turns out that sushi chef, Louis Ling, previously rolled raw fish at Yokohama in East Northport.
