I absolutely LOVE Trader Joe's. It's like a much improved combo of Whole Foods and Fresh and Easy. They sell only their brand of products, and everything is really good. Some items may be a little pricey, but you'll also find great deals. I am addicted to the frozen mac 'n cheese, it is sooooooo cheesy and delicious.
They have a great beer and wine selection. They usually have wine tasting on the weekends as well. Everyone who works there is always so friendly, and you can tell that they love their jobs.
