The Morgan was home to Theodore Kruse's Rainbow Grill, which opened in October 1913. Kruse had closed his Louvre restaurant, a hotspot in the gay community, after it was a focal point of the 1912 Portland vice scandal. The Rainbow advertised "fat, juicy, delicious" oysters and a "Special Men's Grill" with meat of the diner's choosing. It closed in June 1915.[4][5]
