I am a regular TJ's visitor. They have their pros and their cons, but I keep going back because the quality of their food is excellent and their prices are super affordable.
Some of my favorites: Pesto Tortellini Bowl (so good and perfect for lunch), excellent array of protein/snack bars (love me some Luna), Lychee (the only store I know of to sell it...when it's in season), tasty on-the-vine tomatoes, and their Olive Oil Popcorn makes the perfect snack. I also really love that you can mix and match bottles of beer to make your own six pack. Great idea!
All in all, I love Trader Joe's. My only complaint is that their produce isn't always the best. It tends to be somewhat bruised or too ripe so I'd rather go elsewhere for my fruit. But my weekly TJ's visits will definitely continue.
