HACIENDA HEIGHTS, Calif. — The only familiar signs at the McDonald’s in this community are the golden arches, the drive-through, and the menu.

Gone are the plastic furniture, Ronald McDonald, and the red and yellow palette that has defined the world’s largest hamburger chain. Leather seats, earth tones, bamboo plants, and water trickling down glass panels have taken their place.

The makeover elements are meant to help diners achieve happiness and fortune — whether they realize it or not.

That’s because the restaurant was redesigned using the principles of feng shui, the ancient Chinese practice of arranging objects and numbers to promote health, harmony, and prosperity.

The concept is an unlikely fit with fast food. But the restaurant’s owners say the designs are aimed at creating a soothing setting that will encourage diners to linger over their burgers and fries, and come back again.

The makeover is part of the attempt by McDonald’s Corp. in recent years to remodel hundreds of its restaurants to attract more patrons with unique decor and amenities that might entice them stay awhile.

It also fits into McDonald’s larger corporate practice of catering to local tastes, such as a fondue-style burger in France or a pita-wrapped “McArabia” sandwich in the Middle East.

The basic principles of feng shui include placing strategic representations of five natural elements — earth, water, fire, metal, and wood — around the room to increase the flow of chi, or energy. The McDonald’s in this Los Angeles suburb boasts wood ceiling, silver-coated chairs, plus red accents throughout the dining area to symbolize fire and “good luck, laughter, and prosperity,” the designer of the dining area, Brenda Clifford, said.

The textured walls patterned after ocean waves symbolize “life and relaxation — the balanced things that you want in your life,” she said.

Customers are responding positively, whether or not they recognize the feng shui elements.

“When we first walked in we were amazed, we were happy we skipped the drive-through and went inside,” Andrew Chen said while lounging in a white leather booth with a friend.
