I've always wanted to try a White Castle and this is the only place in western US.
The burgers are more like small sliders, so order a few of them. They come with pickles and grilled onions, but they are very tasty!
I also ordered 'onion chips'; Its like onion rings but in French fry form. They are really good.
The service was quick, the prices were reasonable (considering it's on the strip). I would definitely come back.
