I'm a pretty big fan of Trader Joe's and have been shopping at various locations for years. I'd like to point out that the TJ's I used to frequent (Scottsdale, AZ) does not carry hard liquor. So I almost squealed (actually I did) when I saw that the beer and wine wall was longer and had my beloved Knob Creek. I love that you can totally buy booze here. Yeah!
The thing I love most about Trader Joe's is that I trust what they are selling. I view their products as being high quality and low cost. I can write a grocery list and food budget knowing what their prices are going to be. Take milk for instance, a gallon here at regular price is as low as most big box grocery stores charge for milk that's on sale. Same with eggs, butter, yogurt, well you get the idea. Don't show up expecting to buy Coke and Pepsi as TJ's stocks mostly their own brands though they have TJ versions of most major items.
My only problem with this location is that the parking lot during peak hours is messed up and awkward. However Id like to point out that most parking lots in Las Vegas are pretty messed up and make little to no sense. That felt good to get off my chest. The sweet spot visitation time is around 2pm. You can park close to the entrance and there wont be much of a line.
If you've never been maybe do a weeks shopping in there and see what you think. TJ's brand Pesto + Gnocchi + Italian Sausage = hearty amazing dinner.
