Let me start with the fact that I am from Michigan - high quality craft beer is available all over the state. Needless to say - I'm a beer nerd.
Normally when in Vegas your choices are limited to generic overpriced yellow tinted water. Nothing of real substance, then again that isn't why people go to Vegas. So when I was just out there I made it a point to search out and see if there were any breweries around - enter Sin City Brewing.
As far as the atmosphere of their locations - it's nice. They sell some solid merchandise which I did purchase and they do offer flights which I also decided to get. What I will say about the beer is it all felt light - it had a light mouth feel like there was something missing or they were focusing on their average clientele. The biggest disappointment for me was the IPA - I love the higher IBU beers that have life. Everything was just average at best. I do understand my views are a bit biased so keep that in mind.
When in Vegas this might be your best - if not only option for anything craft.
