MAHABALIPURAM, India—B. Vivekanandhan, the 51-year-old owner of a popular restaurant called Moonrakers, is fiercely competing for customers in this South Indian holiday town. So violently, in fact, that fists flew.
His main enemies are his own flesh and blood. His older brother operates a seafood restaurant called Moonwalkers just across the street. Just down the same lane, his younger brother runs Moonrocks. The menus are almost identical.
