I love Trader Joes! A great variety of foods packed in a small space.
Other reviews have covered the healthy and organic foods, so I figured I'd add in some junk food favorites: Tiramisu Torte, Chocolate Lava Cakes, Dark Chocolate covered Expresso beans, Lemon Crisp cookies and Brownie Truffle Baking Mix. Moderation and lots of cardio help.
The staff are great... friendly and helpful! About once a week, I reluctantly ask for someone to retrieve 3 cases of Sparkling Lime Mineral Water (I call it seltzer) out of the back (ie: a heavy, cumbersome pain). Never any hesitation... and usually an enthusiasm that leaves me in envy/puzzled.
I do try to avoid rush hour (4-6pm, sometimes earlier) because the crowd of (small) carts maneuvering small aisles gets crazy. Even then, the Manager/Captain quickly redeploys stockers to open additional registers and keep things moving as well as possible. You have to admire the team working here... I wish other stores could emulate them!
