This place has never disappointed. I come in here all the time for the breakfast. Their stack of pancakes is probably the best ever! So massive and very well priced! There's some contest where if you eat 15 you can get the stack for free, I would never manage but I offer you the challenge! I have also come here on other occasions for their shrimp cocktail. It's massive and can definitely fill you up even though I'm sure it's meant as an appetizer.
The place also has loads of history which is really cool to discover when traveling to a new city. Their menus give a good description of Du-par's and it's legacy in Vegas.
The service here is amazing and there's always a line out the door but you'll get seen to quickly enough. This is my regular joint while downtown.
