Tuna Tacos at Fleur by Hubert Keller

After the Las Vegas outpost of his fine dining restaurant, Fleur de Lys, closed, chef Keller transformed his space at Mandalay Bay into a small-plates concept with inspired worldly dishes, such as the tuna tacos. Each of three hard-shell tacos has a bed of lettuce and cabbage topped with a fresh slice of tuna sashimi and finished with a dollop of avocado cream and a slice of Serrano pepper for a kick. $13 for three, in Mandalay Bay, 632-9400.
