This is candy land for oenophiles and others who enjoy imbibing. My only recommendation would be to organize the wines not just by type, but also region. I enjoy supporting wineries form Central California; it would be nice to just go to the pinot or chardonnay section and have all the Central California wines displayed together.
The staff picks are usually pretty decent. I also appreciate the beer selection. I have found Total Wine cheaper than Costco on most wines and hard liquor.
The staff has always been helpful with finding items. They offer classes (I took several series through UNLV at the Henderson and Rampart stores) and wine tastings.
They also sell kegs.
