I've walked by the Imperial Palace countless times, and I have to say the way in is the most well-kept secret no one cares about on the Strip. Because if you wanted downtown-level cheap gaming you can hit O'Sheas or Casino Royale, and if you wanted cheap liquor, well, you can do that too. Or get blasted at their "rockstar" bar they have opened out to the Strip with the girls pouring Everclear into everything and everything!
It's gross and old and the only thing going for it is Human Nature, which saves this from a one-star doom. Well, that and the guitar-shaped liquor containers that are a must if you're going to cart something gaudy and intoxicating around the strip like a true blue Vegas visitor.
