I'm thinking about stopping by Vegas for just a day. I'll be by myself, gambling during the day. What would be a good way to spend the evening, i.e. bars, clubs?

Depends on what day of the week it is, but any of the bars on the casino floors at the major hotels are great spots to hang, especially if youre by yourself. a few that should be good are the island bar at the palms and even nine steakhouse bar should be a good scene.
