Love the convenience since its close to my place and there really isn't a Lee's Discount around here.
Pay close attention the reviews for this place because they are basically based on preference. For example, if you're looking for a good selection of craft beers this isn't the place. Specialty liquors are a bit limited as well, but as far as the hard stuff, you'll find it here. They have brands like Fireball and JD in a very freezer so you can buy it nice and chilled already.
They have a decent selection of wine but if you're a connesour don't expect to find any rare types. In my opinion they have a larger selection of what I call 'travel size' bottles then Lee's.
The customer service is hit or miss depending on who's behind the counter but let's face it, its a liquor store, as long as you find what you need to get nice you're not gonna care whether or not dude gives you service with a smile.
I haven't had any opportunities to ask any tough questions so I can't gauge the staff's knowledge. The three stars are basically based on price and limited stock on certain staples. Vegas is big on craft, they should expand on that.
Happy drinking...DJR
