My first purchased from ABC was from the Disney Land trip in Anaheim, then Hawaii now in Las Vegas.
As a convenience store, this is the best and the least expensive on the whole LV strip from water bottles, juices, nuts snacks items , little souvenirs , macadamias nuts ( remind me of Hawaii), t-shirts and so on gilts to bring home from the trip.
I believe there are few stores in this LV strip, just look for the sign and it would save you few $ for the H2O purchased (it cost $ 1/ 1L this store, and $ 7/ 1L in the hotel we stayed) Elk!
