This is well just another gas station and convenience store...but it is a good option for buying some necessities vs. paying your hotel prices. If you're staying at a place off of Tropicana this is within walking distance to pick up some simple stuff such as bottled water, small sandwiches and other snacks when you want to eat/drink/stock up on a budget.
I made several walks here from my hotel to buy water and even a cheap $3 sandwich here and there to hold me over when the local liquor store wanted $4 for a gallon of water vs $2 here (not cheap by any means but I'll take it over $4!) and my hotel was selling lame sandwiches for $6.
