What you do need to know is that you need to avoid the stuff on the line that is meant to distract you. Potatoes, Rice, bread, vegetables and anything else that is considered a side dish should be kept to a minimum. Really, do you want to spend $22 for a dinner roll?
Hit the crab legs, hop on the shrimp, devour the prime rib.
If you need to take a break and hit the restroom, so be it. DO NOT BE AFRAID TO UNLOAD!!! People are always so conscious of etiquette. This is a buffet, start eating as much as you can. If you need to make room, blast away.
One more thing, when eating crab legs remember that you are not paying by the pound, do not struggle with a tiny piece of shell that refuses to give up the goods. Move on and get the big stuff.
The Las Vegas buffet is where you can unleash the fury of your seven months of dieting to fit into a swimsuit that you never liked anyway. Ask yourself, is one giant meal really going to make you look fatter. NO!
The real question should be do you need to give up quality by eating at a Las Vegas buffet or can you just go cheap? There are plenty of places where you can get a good meal, that happens to also be cheap. Cheap food in Las Vegas is not scarce it is just not as easy to find. Don't worry, I have plenty of cheap food options that might keep you from going to a buffet.
