ABC stores are mainly from Hawaii but have found there way to the mainland of the United States. This is a great place to buy cheap drinks and food then the overpriced stores inside the hotels and I think this gives the tourists some advantage to save some money and not everyone in Vegas knows about these ABC stores. Friendly services and well stocked store with great deals and friendly staff that are mostly Asian.
I always come for the 1 liter bottled water, tall cans of beer and sometimes six pack and some snacks to go along with the beer. The Cigarettes here are cheaper compared to the ones in the casino and they have great souvenirs to bring back home that won't break the bank.
