Seeking a steak for breakfast? That's easy to find. If the urge to grab a burger strikes at 3:00 in the morning, it's no problem. Las Vegas never sleeps, and, as a result, there's always something to do and somewhere to eat at all hours of the day. "Last call" doesn't really exist in Las Vegas, and, instead, bars and pubs eventually just close their doors for the night (or early in the morning) when things start to slow down.
The casinos are open around the clock, of course, so there's always somewhere to stretch out restless legs, and because the weather is decent year round in Las Vegas, people watching on the Strip and downtown is always an option.
Most stores, clubs, attractions and restaurants have closing hours, but there are always a few that cater to the 24-hour audience, so visitors never have to feel like they are the only ones awake.
