WAKANUI GRILL DINING SINGAPORE serves steak and charcoal-grilled lamb near Shenton Way in Singapore. The kitchen focuses on filet, ribeye, and tenderloin along with charcoal lamb chops, and also offers tuna ceviche and eel. A large family was seated at a long private table, and a 31-person corporate lunch ran on a prix fixe menu. The steak texture is firmer than the lamb.
