What hasn't been said about this place in the 1000 other reviews?
Yes, their food portions really are that big. Yes, their food is amazing and reasonably-priced. And, yes, you can drink here at any time of day or night.
I ordered the onion rings. Most places would give you a manageable portion size. Not here. In typical Vegas fashion, they gave me a trough of onion rings. And they weren't small onion rings. They were massive, breaded, greasy -- just perfect. I must have eaten 5 whole onions.
I highly recommend The Peppermill.
