A Lot of good places there. I recommend if it's late at night, I mean 3am,4am grab a slice of Pizza on the third floor. It's not advertized, the entry is a door. No name...like it's a Secret.
And the Aria has a few joints I like, Javier's and Lemongrass.
But in the corridor going from Paris to Bally's there's a few spot along the way...I never tried any of them.
But where I wouldn't go, in Paris is the Eiffel tower...the view is "meh" food, so, so..kinda overrated if you task me. But if you're with a date, then give it a whack, she'll love the effort.

I'm not a local but the last time I stayed at Paris we walked over another block from the strip to a place called Ellis Island.  It looked like the kind of place locals would go to gamble and it was a ton of fun.  Laid back dealers and they brew their own beer.  It's 100 times smaller than a strip casino but we had more fun there than we did at Caesars or anywhere on the strip.

I will say the service at Paris (I think all the Caesars properties) really has taken a dive.  They don't offer laundry service, very limited and slow room service.  No bell hops or anywhere to check luggage from 10pm to 8am.  They blamed it on Covid, but honestly, they just aren't paying employees enough to stick around I think. I was disappointed.
