i know, i know, i'm always the grump in the group. but that is not what was called loco moco. that is more in the line of hamburger plate w/egg. i've had many many many of them and still do. what loco moco was and i hope still is but i've heard otherwise is that you had a big foam cup approx 5 inches high and about 5 inches across, more or less, about 2/3 filled with rice. then a hamburger put on top of that, then a egg on top of that and then a large amount of gravy over that. it was portable and good. lived in hawaii for near 18 years and never heard a plate like that called loco moco. loco moco meant that conncoction was in a big foam cup that you could eat on the run, or not. course this does not take away from what you made, awesome, as it seems that a plate like that has morfed into being called loco moco now.
