Eating really good bar food in a fancy-pants Champagne lounge decorated with David LaChapelle photos from Elton John’s personal collection is the kind of experience that only happens in Las Vegas. So is eating really good bar food while sitting next to well-heeled bachelorette parties as celebrities like Brandon Flowers and Shania Twain relax undisturbed in the upstairs catbird-seat booth.

This is Caesars Palace’s Fizz, decked out by creative director David Furnish, John’s longtime domestic partner. With a cozy-for-Vegas 2,750-square-foot setting inspired by a Champagne flute and walls covered with metallic tones and skull-themed images, it feels like you’re hanging out in an extremely eclectic wealthy person’s home, which is kind of the point.

While this could indeed be your Veuve and Osetra spot, the $11 plate of four roast beef and horseradish panini bites with watercress and Swiss cheese offers more accessible decadence on a menu created by John and Furnish’s personal chef, Gauthier Bialek. This is rarefied finger food that looks a bit deceptive. The ciabatta bread seems thick at first glance, like it would overwhelm the thinly sliced beef. But it doesn’t: The richness of the beef and the kick of the horseradish cream is what you’ll taste in every bite.

Muffaletta panini bites ($10) pack ham, salami, mortadella, provolone and kalamata olive tapenade onto focaccia for another nicely balanced morsel. Over-the-top desserts like the Creme Fizz ($12) with caramel mousse and vervain creme crowned with hazelnut brittle and white chocolate are worthy of Paris cafés where people linger for hours with no plans for the day except eating lots of sweets. Plus, this is a bar where it’s easy to have a conversation, so maybe order Champagne and take your time.

Fizz Caesars Palace, 702-776-3200. Sunday-Thursday, 5 p.m.-2 a.m.; Friday & Saturday, noon-4 a.m.
