River City Casino sits in Lemay, about ten miles south of downtown St. Louis, and it is the highest-searched casino in Missouri. It rates 4.1 from close to 10,000 Google reviewers, which puts it at the top of the St. Louis cluster on visitor sentiment.

The property reads as a locals' casino with a good hotel attached rather than a destination resort. That is a compliment — the floor is easy to navigate, parking is straightforward, and it does not carry the weekend crush of the downtown properties.

What's on the floor

The gaming space runs to about 90,000 square feet, with roughly 2,000 slot machines and 55 table games. That table count is the largest in the immediate St. Louis area, and the pit tends to keep more games open on weeknights than its neighbours do.

The poker room is deliberately low-stakes and beginner-friendly. The listed games are $1/$3 no-limit Texas Hold'em with a $60 to $300 buy-in, and $4/$8 limit Hold'em with a $40 buy-in. If you are learning, or you want a room where a small bankroll lasts an evening, this is a more forgiving setting than the bigger Missouri rooms.

A sportsbook opened at the property in December 2025, when retail sports betting launched across Missouri.

Hotel and dining

The hotel is a AAA Four Diamond full-service property, which is a genuine differentiator in this market — most Missouri casino hotels sit a tier below. The property lists seven restaurants spanning an upscale steakhouse, Italian and casual dining.

Why the poker room stands out

Most casino poker rooms in a metro this size push toward $2/$5 and above, which quietly prices out anyone learning the game. River City does the opposite. A $1/$3 no-limit game with a $60 minimum buy-in, sitting next to a $4/$8 limit table with a $40 buy-in, is close to the friendliest structure you will find in Missouri — and limit Hold'em in particular has become hard to find anywhere.

If you are teaching someone the game, or coming back to it after years away, this is the room in St. Louis to do it in.

Tips before you go

You must be 21 to gamble, which is the minimum age at every Missouri casino.

The floor runs 24 hours, with one quirk worth knowing: it closes from 5am to 6am on Wednesdays for maintenance. That is the only scheduled break in the week, so a late session any other night runs straight through.

If you want a table rather than a machine, weeknight evenings are the sweet spot: enough traffic that games are running, not so much that you are waiting for a seat.

Nearby alternatives

North-west of the city, Hollywood Casino St. Louis in Maryland Heights is the largest floor in the metro. Downtown, Horseshoe St. Louis is the closest option to the arch and the ballpark. Further out, Ameristar Casino Resort Spa St. Charles is the resort pick, with a spa and the largest hotel of the group.
