Trader Joe's is pretty much amazing. Everything is healthy and affordable, and there are so many unique products that you can't find anywhere else.
They also always have samples of at least one food item and one beverage. (Warning: if you try the samples, there is a good chance you'll be leaving with a bag, box, or bottle of whatever it was.)
The frozen prepackaged meals can be hit or miss. It's not that they are gross, if anything, just lacking in flavor. When in doubt, hit up the samples table! If you visit enough, over time, you'll probably be able to try just about everything before you buy.
The parking garage is a little tight, so I like going on foot to avoid having to park, but it's doable.
