Carson City Saloon is a spacious, divey sports bar with multiple levels and televisions, as well as a large projection screen for sporting events and a rooftop bar that is great during nice weather.
The food here is not good and should only be eaten in emergencies such as starvation and extreme intoxication. Despite the very reasonable prices, the execution of the menu items aren't worth what you pay for them. Like I said, it's only good for keeping you from getting sick while you're pounding drinks.
On the other hand, the service is excellent and attentive. I was there during a Stanley Cup Finals game, and although there were only a few servers on the floor, they were doing an excellent job keeping up with the crowd's demands, maintaining tabs and remaining upbeat the entire time. As for the ambiance, the music gets a little loud when they aren't piping in the game's audio, the smoking gets heavy, the crowds get thick and the nightclub vibe is in full effect as the evening draws on.
My opinion is that this is a divey club disguised as a sports bar that has plenty of floor space for watching games, but ultimately caters to a younger crowd. If you decide to watch the game there, do yourself a favor and eat somewhere beforehand, then get ready to get rowdy!
