Great beer and location in the Miracle Mile!
I won't go so far as to say that the beer at Sin City Brewery is great, but it is pretty good and they have a few choices.
The Brewery has a Yelp deal that offers 50% off your first pint of beer when you check-in. They also give a free beer when you purchase a shirt. So unlike most places in Vegas where you lose your shirt, Sin City Brewery will help clothe you and keep you on an even keel.
This is my 5th or 6th time here and each time I have enjoyed the company of the bartender and the chance to people watch from the bar. I have also found that the people I meet here are all for some reason open to talk to strangers. So I always have a great conversation with either the bartender or my fellow patrons.
Last night our bartender was the best so far. Her name is Mo and I hope she is still there on my next trip to Vegas.
