Four stars because this place has such a great atmosphere! Many things can make a bar a great bar. The food. The drinks. The people. etc... For Boulder Dam Brewing Co. it is definitely the people. My boyfriend and I went twice while in Vegas and both times everyone was super friendly.
The beers are nothing complicated. Solid and consistent. Good if you are a fan of that yeast character but if you're not then you may not be a fan of the beers.
The food also is pretty decent. I would recommend the pretzel and the wings. I'm also a big fan of the fact that smoking is only allowed outdoors. As a New Englander no longer used to smoking in her bars, this was a great break from the other bars in the area.
Stay friendly Boulder Dam Brewing!!
