Same Ice, Three Addresses
Minus5 runs three Ice Bars in Las Vegas and the rooms themselves are close enough to a coin flip: ice walls, ice seats, ice glasses, a parka and gloves handed to you at the door, and a temperature the brand named itself after, minus 5 Celsius, or about 23 Fahrenheit. So the choice isn't which ice bar is best. It's which one sits where you already are. We've lined them up north to south down the Strip, because that's the only axis that actually decides it.

The Venetian: Ice at the End of the Canal
Minus5 at the Venetian is tucked into the Grand Canal Shoppes on Level 2, right at the end of the canal across from Skechers. That address is the whole argument for it: you walk the length of the painted-sky canal, past the gondolas and the singing gondoliers, and then step through a door into a sub-zero room. Nowhere else on the Strip stacks fake Venice and a walk-in freezer that tightly. Pair it with a gondola ride and you've got an afternoon that needs no car and no plan.
Best for: anyone already deep in the Venetian or the Palazzo, and couples building a mid-Strip indoor day.
Where: Grand Canal Shoppes, Level 2, end of the canal | Ages: 7 and up before 9 p.m., minors with an adult | Walk-in: Indoors the whole way

The LINQ Promenade: The Shock-of-Contrast One
Minus5 at the LINQ sits on the open-air promenade between Brooklyn Bowl and In-N-Out Burger, and that detail is the reason to pick it. The other two you reach through air-conditioned resort corridors, so the ice is a pleasant surprise. This one you reach off a hot outdoor walkway in full desert sun, which means you go from roughly 110 degrees to 23 in the time it takes to open a door. Same room, completely different jolt.
Best for: High Roller and LINQ crowds, and anyone who wants the temperature swing to actually register in their body.
Where: LINQ Promenade, between Brooklyn Bowl and In-N-Out | Ages: 7 and up before 9 p.m., minors with an adult | Walk-in: Off an outdoor promenade

Mandalay Bay: The South-End Fix
Minus5 at Mandalay Bay lives in the Shoppes at Mandalay Place, up above the escalators near the House of Blues. This is the far south end of the Strip, and that geography is genuinely the point: if you're staying at Mandalay Bay, Luxor or Excalibur, the other two Minus5 rooms are a real trek and this one is a corridor walk. It also sits in the same complex as the Shark Reef Aquarium, which makes a tidy pairing when you've run out of reasons to be outside.
Best for: the south-Strip resorts, and anyone stitching together an indoor afternoon around Mandalay Place.
Where: Shoppes at Mandalay Place, above the escalators | Ages: 7 and up before 9 p.m., minors with an adult | Walk-in: Indoors the whole way
The Practical Truth
Stop overthinking it and use your hotel: Venetian or Palazzo, go to the Venetian; anywhere around the LINQ or Caesars, go to the LINQ; Mandalay Bay, Luxor or Excalibur, go to Mandalay Place. This is the pick that costs you the least walking, and since the rooms are near-identical, walking is the only thing you're really trading. One thing worth knowing before you go: the 7-and-up family window closes at 9 p.m., so an ice bar with kids is a daytime plan, not a nightcap -- and the room gets noticeably more adult after that cutoff. Check the booking section below for current availability at all three. Already committed to the Venetian for the day? Our two most romantic things to do in Las Vegas starts a few hundred feet from that same door.
