The story of Honolulu's Rainbow Drive-In, a favorite of President Barack Obama.
An Army cook built the most famous lunch counter in Hawaii. Almost NOBODY can say his name.
You know the sign. The neon rainbow off Kapahulu Avenue, at the edge of Waikiki, glowing over the same window since 1961. You have stood in that line. Your parents stood in it. Maybe their parents did too.
The man behind it was born in Hawaii on April 3, 1915, and raised in Okinawa. When Seiju Ifuku came back to the islands, he joined the U.S. Army. World War II handed him the least glamorous job a soldier can carry.
He cooked.
He served with the 100th Infantry Battalion, the Japanese American unit that bled so hard through Italy and France it became known as the Purple Heart Battalion. Other men carried ri**es into history. Seiju carried pots. Somebody had to keep those soldiers on their feet.
The war ended. He came home and did not stop cooking. He worked other men's kitchens, then ran a small drive-in of his own on Kalakaua Avenue. And on October 2, 1961, with his wife Ayako, he opened a little counter at the corner of Kapahulu and Kanaina avenues.
Their son named it. The family lived in Manoa Valley, where the morning rain hangs rainbows over the ridge, so the boy said: call it Rainbow.
The menu was loyalty disguised as a business plan. Chili and rice, 50 cents. Hamburgers, a quarter. Barbecue beef plate, one dollar. Waikiki was turning into a glamour capital one block away, and Seiju aimed his kitchen the other direction - at construction workers, nurses, surfers, families counting change on payday.
The family still repeats his philosophy word for word: "Make it cheap, sell a lot and rely on volume."
A restaurant man at the entrance to Waikiki chases the tourist dollar. That is the obvious move. Seiju Ifuku spent thirty years refusing it, piling gravy over two scoops of rice for people who had been swinging hammers since dawn.
He retired around 1990 and handed the tongs to his family.
On August 18, 2004, Seiju Ifuku died at 89. They buried him at Punchbowl, the National Memorial Cemetery of the Pacific. An Army cook, laid down among the soldiers he once fed.
The restaurant became an institution. The man stayed invisible.
The whole island can describe the rainbow on his sign. Almost no one can name the cook underneath it.
Every local family has an order they recite at that window without thinking - and a grandparent who paid 50 cents for the same plate.
Then, five years after he died, reporters crowded a returning hometown boy and asked what he wanted to do first. He had grown up eating plate lunch in Kapahulu. Now he was President of the United States. Barack Obama said, "I'm going to get a plate lunch." The crowd cheered.
Today the Kapahulu window alone sends out more than 1,000 plates a day, and Rainbow Drive-In has spread to locations across Oahu. Seiju's grandson Chris Iwamura runs it now, third generation, same recipes. For the 60th anniversary, in the middle of the pandemic, the family gave a dollar from every plate sold to local schools. "We've always tried to take care of the community and our employees as much as possible," Chris says.
Some men come home from war and put down the work the Army gave them. Seiju Ifuku picked his up every morning for the rest of his life. He fed a battalion at war. Then he fed an island, plate by plate, priced so no one was turned away. The rainbow still comes on at dusk. His kitchen has never stopped.
