The Tokyo-based Mars salon recently opened its first U.S. location on Melrose Avenue in West Hollywood, offering high-end gel manicures starting at $80, along with custom nail art in a luxury setting. Each customer has a private room, with a television, where two technicians work at one time. It's not uncommon for clients to come in with clothing they want their nails to match. One woman brought in a picture of a beaded Diane von Furstenberg top. The technicians were able to mimic the color and 3-D nature of the floral beading in the nail design. "Later, Diane [von Furstenberg] tweeted about it," says Hiroko Fujikawa, the owner of Mars.
