Doc ~ How did Loco Moco get it name? So you know how this originate? Thank You Doc

Well, Aunty only knew that Loco Moco was originated on the Big Island in Hilo, but there were several different claims of which restaurant actually served the first loco moco. Here's one source, which says it was created at a long-gone diner called the Lincoln Grill. And another article.

Others claim that the name was invented by Cafe 100. The dish has been around for a long time (the rice, hamburger steak and gravy part), it just never had a name until the 1970s.

Now loco moco is a ubiquitous part of the local Hawaiian menu.
