'Worlds Largest Gift Shop' looks a lot better on a sign than '2-1/2 Miles of Crap'.
Now, don't get me wrong, I like this place. It is filled with all sorts of stuff that wouldn't fly in casino gift shops anymore (and that's a shame because good kitsch goes a long way towards building memories). You have all manner of goods up to and including green card visors, leather moccasins and obnoxious t-shirts, with hundreds of things in between.
Asking for help at this place is like asking a clerk at The Salvation Army to do an inventory check; it ain't gonna happen, chief. Know that going into it. There's also a security guard at the door and you'll have to check your bag (because apparently low cost touristy crap is in high demand on the black market).
But, uh, yeah. If you have a mess of people demanding you bring them something back from Sin City, you could do worse than TWLGS..
