Lou's is a charming little diner near Decatur/Alta next to Walgreens. When I used to work at Western HS we would meet here every Friday morning at 6 am and did so for several years.
Over the years I've tried the eggs, omelets, chicken fried steak, oatmeal, bagel and fruit combos, but the real stand-out is their skillet breakfast. They also offer grits in lieu of potatoes.
The other breakfasts are truly average, but the skillet is loaded with hash browns, your choice of meat, (your choice of anything else actually - onions, peppers etc) loaded with cheese and topped with eggs any style.
Lou's probably rates 3* but I'm bumping it up one because it's the best skillet I've found thus far in Vegas (and also I see my priest in there occasionally - don't know why that influences me, but for some reason it does).
