We went for breakfast, and I swear it was more like early lunch by the time we finished. Although they didn't seem particularly busy, they might have been understaffed in the kitchen or on the floor. It took our server many moons between appearances, and it was overall a sloth-like breakfast service.
We were drawn in by the low prices outside and didn't want to insult Vegas by doing McD's on day 1. We figured it couldn't be that bad, and we were right, but it also wasn't that good. There's an array of $6 menu items and a two-for-one drink deal ($10). I chose the mimosa and the mojito; he chose the mimosa and the Almond Joy (overwhelming Kahlua taste).
I had the biscuits & gravy, which were very mediocre. I guess it wasn't a fair choice since I grew up with Southern cooking, and bland gravy is a crime. I splashed Tabasco on to make it more interesting.
Just keep wandering or accept that your meal will be very average and very slow. This is nothing above diner food for breakfast. I think I've had better from IHOP.
