The restaurant in this little locals casino has some of the best burgers you'll find in town at a reasonable price.
My favorite is the bacon double cheeseburger. I'm a big guy and this is almost too much food for me which really says something.
Two big pattys- I'm guessing 1/3lb each, so a total of 2/3lb of really good quality beef and your choice of cheese. What really makes this burger outstanding though is the perfectly cooked thick cut bacon. Two large strips of awesomeness criss-cross the top of the burger. Build the rest yourself with the lettuce, tomato, and onion provided on the side. I like some mayo to finish it off and you're good to go.
I haven't found a better BDCB in Vegas yet.
