I go here pretty much once a week. It is sort of a particular store- not very good for produce- most of it is packaged in way too much plastic and you have to buy in larger quantities. However, they have 19cent bananas and i often buy bell peppers there. I won't buy strawberries there as they are almost always have gone off or picked while green and never ripen properly.
The things that I love about Trader Joe's:
Cheese! They have the best prices on cheese that I have seen (except for Costco, of course)
Yogurt! Ohmygod the organic vanilla yogurt is the best yogurt I have ever had. I often eat it for dessert with some fruit- absolutely heavenly.
Red Thai Curry sauce, dried fruits, salmon roulade, raspberry creme brulee, etc etc
They have so many unique products that are just wonderful, I would cry cry cry if I couldn't go to Trader Joes anymore.
They also have nice succulents in cute pots outside and their flowers are gorgeous and super cheap. I always look forward to spring when they have daffodils- something like 10 for $2? Can't beat that.
