They're no strangers to these parts, having run a popular food truck before, but Jerry and Jackie Lau's food stall inside Mills Market is proof that they're here to stay. Kai Kai shines a spotlight on Cantonese cooking. Not sure where to begin? Take one look at that case of barbecue and roasted meat tempting from just behind the counter and it becomes clear. Sold by the pound or as a meal with steamed rice and two or three selections (crispy pork, soy sauce chicken, and char siu are go-to choices), the menu also includes noodle and rice dishes, as well as an entire section devoted to dim sum. Roast duck bao is a surprising delight, as is the fried mochi pork dumpling with just a hint of sweetness that delivers an impactful bite.
