[This is specific to Ocarina of Time but can be easily adapted]
Meiko is a half-Gerudo woman, which is obvious from her height and tan skin. However, she has the dark hair and eyes of her late father.
Mei owns a bar, simply named the Back Alley Bar, located on one of the quieter side streets in Hyrule Castle Town. When Link comes by as a child, she insists he shouldn't be there -- but doesn't kick him out. She just won't give him anything but a glass of LonLon Milk (and for free, unless he insists on paying). Most of her customers pop in only at night, including the Happy Mask Salesman, who honestly freaks her out.
After the time skip, Mei is one of the Castle Town refugees making it by in Kakariko Village. She would like to open her bar again someday, if they all live to see another time of peace.
