When you think "St. Louis," gambling is probably not the first thing that comes to mind. Standing exactly where Lewis and Clark started their journey? Sure. A ride to the top of Gateway Arch for a view of the city at 630 feet (190 meters) [source: ESL]? Why not. Tour of the Anheuser-Busch Brewery, with samples? Obviously.
But high-stakes gaming?
Yep. St. Louis has three casinos, and another three live right nearby [source: SLA]. They're all "Vegas-style" joints with hotels, restaurants, entertainment, spas and shopping on-site [source: ESL]. There's one right across from Gateway Arch, so a quick (or not-so-quick) game of poker isn't out of your way at all.
If you bring the kids (or even if you don't), don't miss the city's interactive children's museum, the Magic House. The Oval Office replica alone is worth a visit.
