The new Amex 1850 Lounge at the Aria Las Vegas just opened last week and luckily I'm already in town for F1 so you know I had to go check it out. How can you not when there's free food and drinks to be had, right? Last year, Chase Sapphire also hosted a pop-up lounge around the same time so it was fun to see the comparison between the two lounges and what they offer.
