My grandma specifically requested some Ethel M chocolate to be brought home from a recent trip to Vegas. This chocolate is a classic and the fact that there's a location in the airport makes it super convenient to get.
When you walk in, you get a free sample of whatever chocolate you'd like. They've got pre made boxes and a wall full of candy bars. I love the nougat and caramel bar. Yum!
You can create your own box of chocolate. Each piece is $2. I like the Pb&J chocolate. They've even got some alcohol flavors like tequila or bourbon. If you want to hand pick your box, the smallest size is a 16 piece but you can buy them individually.
