Great décor and even better drinks. All cocktails cost a reasonable flat rate, are well-prepared, garnished properly, and are tasty as hell. They also have an alcohol content rating system so you can plan your orders accordingly. I'm a lightweight so even the mildest level cocktails induce tipsiness.
The interior can be extremely dark, but that probably enhances my looks. It's only a short cab ride from Fremont street and worth the visit.
