This remains the gold standard for breakfast in Las Vegas, and in fact the whole country. I would say it's 2nd only to Bryant's Breakfast in Memphis, so definitely #1 West of the Rockies. As I've mentioned before, go here the morning you're leaving: no chance you'll feel hungry on the plane flight home, however long it is.
I've been migrating from the popeye lately to the king of hearts omelet (which is with artichokes and jack cheese.) I've also found you can get a "small" omelet if you ask for it, which comes on a small plate, but I think has the same amount of fillings, just fewer eggs (it only costs a few cents less, but a full-size omelet probably has a week's worth of eggs unless you get egg whites.) The potatoes were better this time around...so I added the star back, although service was spotty (but friendly.)
My friend who was visiting Vegas this week liked it so much he insisted on coming here 3 mornings in the 4 days he was in town.
And don't forget the pumpkin or banana bread instead of toast...that's essential here.
