Depends where you’re staying.
On the south end of the Strip, the cheap tables are gonna be in Excalibur, Hooters and Tropicana.
On the center of the Strip, there’s a ton of budget properties grouped together. Anything north of Paris and south of Venetian (and on that side of the road) is all budget properties. I’m talking about Bally’s, Harrah’s, Flamingo, etc.
On the north end of the Strip, Circus Circus and Stratosphere.
If you’re willing to leave the Strip, there’s tons more options.
Las Vegas is pretty big. It’s kinda hard for us to give you specific information without us getting more details first.
