I love Gold Mine. It's close to my house, and has a great local vibe which can be hard to find in a town of large casinos, clubs and bars. A true neighborhood dive. It isn't for everyone, as the crowd is very diverse given the night. I love Wednesday nights (free pool and ladies' night!), and the weekends offer live music on their patio. This is definitely a spot to go with friends. You can hang out and do your own thing or mix in with the crowd and meet new people.
Drinks are cheap, and bartenders are friendly. Only thing is you never know when they'll close up for the night. Sometimes they'll stay open until 2, sometimes it's midnight. Difficult to gauge, which sucks for someone who doesn't get out until past 10 (like myself).
Tom and Shotty are quick to learn your name and drink. Beer on tap has a smaller, but decent selection to please everyone (PBR to Stone, cheap to craft), and on a night with a special, it's a great place to hang out in a casual, fun atmosphere.
