Sometimes we try out places we've seen on TV and are disappointed. We saw Hash House A Go Go on Man V. Food AND Rachel Ray's Vacations and were really pleased with the results when we stopped for a late breakfast.
They actually have a "late breakfast" menu. Eggs are only served scrambled for late breakfast, but that was fine with us. They're served a little soft -- "custard style" I've heard it called before -- so if you want them firmer, you should probably order them that way. But they're great as they serve 'em.
Portions are just as huge as you've heard they are. And the prices are so reasonable it doesn't matter if you don't eat it all and have no refrigerator in your hotel room. You won't feel like you've spent tons of money on food you couldn't finish. They charge a split charge ($2.50) and if you're eating with someone who wants the same thing, it's probably worth splitting it.
We ordered a corned beef hash (served on halved potatoes with a biscuit the size of a large orange) and french toast combo (served with eggs, 2 pieces of bacon and a banana sliced in half and roasted, served in the skin), and both were great. And the service was so friendly and quick!
We went on an off day (Wednesday) and waited just five minutes, but I can imagine a longer wait during busier times. Still, it's worth a wait and I'm sure we'll be back next time we're in Las Vegas!
